The Love Hypothesis is set in modern-day America and follows Olive Smith , a 26-year-old graduate student of biology at Stanford University. Olive’s research focuses on pancreatic cancer, but each chapter begins with a hypothesis about Olive’s love life or choices as is relevant to the chapter’s contents.

Two years before the main events of the story, Olive’s expired contacts act up right before her interview for Ph.D. candidacy at Stanford. While she waits in the bathroom for her eyes to stop watering, she meets Adam Carlsen , one of the foremost biology researchers in the world—though she doesn’t learn it was him until the end of the book. His wise words convince Olive that grad school is the right path, and two weeks later, she accepts an offer to study at Stanford.

Almost three years later, Olive is trying to convince her best friend that she’s over her ex-boyfriend so her friend, who is interested in her ex-boyfriend, will date him. Olive is working in the lab on a night she said she’d be on a date when she sees her friend walk by. Desperate to appear on a date, Olive kisses the first man she sees, who turns out to be Adam. Adam has a reputation for being mean and terrifying, and he demands an explanation. Olive haltingly explains her situation, apologizes for the kiss, and runs away, hoping she never sees him again.

A few days later, Olive’s friend corners her in the lab. Before Olive can spin an explanation, Adam arrives and acts warmly toward her, which convinces Olive’s friend their relationship is genuine. Olive wants to keep up the charade until her friends are solidly together, and Adam needs to convince Stanford he’s not leaving to get his research funds unfrozen. The two decide to pretend they’re dating for a month in hopes their fake relationship will be mutually beneficial.

Olive’s area of focus is early detection for pancreatic cancer. Her mother died from pancreatic cancer because it was found too late, and Olive dedicates her life to the disease so other people don’t lose loved ones to it. Needing a better equipped lab for the next phase of her research, Olive contacts several professors at other universities, but only one responds—Tom Benton from Harvard. He’ll be visiting Stanford in a couple of weeks, and Olive frantically works on her project in the hopes he’ll give her space in his lab.

Meanwhile, she keeps up appearances with Adam, meeting him at the campus coffee shop once a week. At their second fake date, Tom Benton joins them. It turns out that he’s a friend of Adam’s and wants to meet this girlfriend everyone’s been talking about. After listening to her research pitch, Tom requests a report by the end of the week, which Olive delivers. A few days later, Tom offers her a spot in his lab next year.

Olive receives an email regarding a paper she submitted to an upcoming conference in Boston. Her paper was accepted for a panel, which means she’ll need to give a speech. She’s terrified, but Adam helps her prepare until she feels more ready. Olive’s friends found other accommodations for the conference, which leaves Olive to share Adam’s hotel room. Olive’s panel overlaps with the keynote speech, and Adam is the keynote speaker, which means he won’t be able to attend as he promised he would.

After the panel, Tom approaches Olive and forces himself on her. When Olive pulls away and threatens to report him, Tom threatens to publish her research under his name and insults her, calling her mediocre and talentless. Adam finds Olive crying in their hotel room. Olive tells him what happened but not who insulted her. They spend the evening together. He shares a similar story from his grad school years, and they make love.

Olive spends the next few days dealing with her emotions, breaking things off with Adam because she feels it’s the right thing to do. When she finally meets up with her friends, they hear Tom’s insults, which Olive accidentally recorded after the panel. They convince Olive to tell Adam the truth and report Tom. Tom is fired from Harvard, and Olive and Adam get back together. Olive finds a new lab placement closer to Stanford, and the two stay in California together.

• " The Love Hypothesis " grabbed the attention of romance readers everywhere in 2021.
• It was named Amazon's Best Romance Novel of 2021 and was nominated for a Goodreads Choice Award.
• This book checks off all my boxes for a great romance read and is definitely worth the hype.

This year, Amazon named " The Love Hypothesis " by Ali Hazelwood the best romance book of the year. Even though it was only recently published in September 2021, "The Love Hypothesis" has quickly become a fan-favorite, with 88% of Goodreads reviewers giving it four- or five-star-level praise .

It was also nominated for a Goodreads Choice Award and is hugely popular amongst Book of the Month members , with only 1% of readers giving it a "disliked" rating.

"The Love Hypothesis" is about Olive Smith, a third-year Ph.D. candidate studying pancreatic cancer at Stanford. In an attempt to convince one of her best friends that she's moved on from an old crush, she impulsively kisses Dr. Adam Carlsen, the department's notoriously brutal (but undeniably attractive) professor. After the kiss, Adam and Olive agree to fake a relationship so she can prove to her friend that she's happily dating and he can convince their department that he isn't planning to leave anytime soon.

I'm a little picky about my romance novels , so giving this read every bit of a five-star review didn't come lightly. My standards are high because the best romance novels have the potential to expose readers to authentic and imperfect relationships and offer new topics of discussion without making us feel like it's a story we've already read. 

With all the hype surrounding this new romance read, I couldn't resist picking it up.

Here's why "The Love Hypothesis" is one of my favorite recent romance books:

1. the story focuses a lot on olive and adam's lives outside their romance, making their love story more believable and interesting..

Romance novels tend to fall into a few popular tropes such as " enemies-to-lovers " or "forbidden love." "The Love Hypothesis" combines two of the most popular tropes right now, "Fake dating" and "grumpy/sunshine," really well — I loved the contrast between Adam's serious attitude to Olive's bright and sugary one. 

But despite following these tropes, the story feels fresh because it's also largely about Olive's work and its meaning to her. The only other romance book I've read featuring a STEM heroine is "The Kiss Quotient" , so I loved seeing that representation and learning about something new. 

The story honestly reflected the challenges Ph.D. candidates face in academia and that authenticity — deepened by the author's personal experiences — brought the characters, the settings, and the romance to life even more as Olive and Adam faced challenges with funding, time-consuming research, and questioning their sense of purpose.

2. The steamier scenes are also awkward and realistic, which made them even better.

In romance books, there are a few different levels of how graphic a steamy scene can get , from little-to-no detail to explicitly outlined movements. (I personally prefer mine to "fade to black.")

There was only one chapter with adult content, and it was definitely graphic. While I made a ton of ridiculous faces while reading and tried to skim past the parts that made me audibly gasp, I loved that it wasn't a movie-made, perfect sex scene with graceful movements and smooth dialogue. The scene was a little awkward, imperfect, and full of consent and conversation, making it refreshingly real.

3. The book deals with other topics besides the main love story, making it a much deeper read.

While it's wonderful to get swept up in the magic of a romantic storyline, having a secondary plot that addresses real issues is what makes a romance novel truly great . 

Mild spoilers and content warnings ahead: While "The Love Hypothesis" is a fun romantic read, it also addresses the pain of familial death, power differentials, intimacy challenges, and, most prevalently, workplace sexual harassment. 

Love is beautiful, fun, and amazing, but "The Love Hypothesis" takes the opportunity to also include conversations about serious issues. While these topics may be tough for some readers, I think these plot points, hard conversations, and complicated emotions take "The Love Hypothesis" to the next level and make it a five-star read. 

The bottom line

"The Love Hypothesis" has everything I personally look for in a romance novel: A unique storyline, authentic characters, and an important message. If you're looking for a perfectly balanced romance read, "The Love Hypothesis" is worth the hype and definitely one of the best romance books to come out in the past year.

The Instant New York Times Bestseller and TikTok Sensation! As seen on THE VIEW! A BuzzFeed Best Summer Read of 2021 When a fake relationship between scientists meets the irresistible force of attraction, it throws one woman’s carefully calculated theories on love into chaos. As a third-year Ph.D. candidate, Olive Smith doesn’t believe in lasting romantic relationships–but her best friend does, and that’s what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof.

Which is why Olive is positively floored when Stanford’s reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive’s career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding…six-pack abs.

Chapter One

Hypothesis: When given a choice between A (a slightly inconveniencing situation) and B (a colossal shitshow with devastating consequences), I will inevitably end up selecting B.

In Olive's defense, the man didn't seem to mind the kiss too much.

It did take him a moment to adjust-perfectly understandable, given the sudden circumstances. It was an awkward, uncomfortable, somewhat painful minute, in which Olive was simultaneously smashing her lips against his and pushing herself as high as her toes would extend to keep her mouth at the same level as his face. Did he have to be so tall? The kiss must have looked like some clumsy headbutt, and she grew anxious that she was not going to be able to pull the whole thing off. Her friend Anh, whom Olive had spotted coming her way a few seconds ago, was going to take one look at this and know at once that Olive and Kiss Dude couldn't possibly be two people in the middle of a date.

Then that agonizingly slow moment went by, and the kiss became . . . different. The man inhaled sharply and inclined his head a tiny bit, making Olive feel less like a squirrel monkey climbing a baobab tree, and his hands-which were large and pleasantly warm in the AC of the hallway-closed around her waist. They slid up a few inches, coming to wrap around Olive's rib cage and holding her to himself. Not too close, and not too far.

It was more of a prolonged peck than anything, but it was quite nice, and for the life span of a few seconds Olive forgot a large number of things, including the fact that she was pressed against a random, unknown dude. That she'd barely had the time to whisper "Can I please kiss you?" before locking lips with him. That what had originally driven her to put on this entire show was the hope of fooling Anh, her best friend in the whole world.

But a good kiss will do that: make a girl forget herself for a while. Olive found herself melting into a broad, solid chest that showed absolutely no give. Her hands traveled from a defined jaw into surprisingly thick and soft hair, and then-then she heard herself sigh, as if already out of breath, and that's when it hit her like a brick on the head, the realization that- No. No.

Nope, nope, no.

She should not be enjoying this. Random dude, and all that.

Olive gasped and pushed herself away from him, frantically looking for Anh. In the 11:00 p.m. bluish glow of the biology labs' hallway, her friend was nowhere to be seen. Weird. Olive was sure she had spotted her a few seconds earlier.

Kiss Dude, on the other hand, was standing right in front of her, lips parted, chest rising and a weird light flickering in his eyes, which was exactly when it dawned on her, the enormity of what she had just done. Of who she had just-

Fuck her life.

Fuck. Her. Life.

Because Dr. Adam Carlsen was a known ass.

This fact was not remarkable in and of itself, as in academia every position above the graduate student level (Olive's level, sadly) required some degree of assness in order to be held for any length of time, with tenured faculty at the very peak of the ass pyramid. Dr. Carlsen, though-he was exceptional. At least if the rumors were anything to go by.

He was the reason Olive's roommate, Malcolm, had to completely scrap two research projects and would likely end up graduating a year late; the one who had made Jeremy throw up from anxiety before his qualifying exams; the sole culprit for half the students in the department being forced to postpone their thesis defenses. Joe, who used to be in Olive's cohort and would take her to watch out-of-focus European movies with microscopic subtitles every Thursday night, had been a research assistant in Carlsen's lab, but he'd decided to drop out six months into it for "reasons." It was probably for the best, since most of Carlsen's remaining graduate assistants had perennially shaky hands and often looked like they hadn't slept in a year.

Dr. Carlsen might have been a young academic rock star and biology's wunderkind, but he was also mean and hypercritical, and it was obvious in the way he spoke, in the way he carried himself, that he thought himself the only person doing decent science within the Stanford biology department. Within the entire world, probably. He was a notoriously moody, obnoxious, terrifying dick.

And Olive had just kissed him.

She wasn't sure how long the silence lasted-only that he was the one to break it. He stood in front of Olive, ridiculously intimidating with dark eyes and even darker hair, staring down from who knows how many inches above six feet-he must have been over half a foot taller than she was. He scowled, an expression that she recognized from seeing him attend the departmental seminar, a look that usually preceded him raising his hand to point out some perceived fatal flaw in the speaker's work.

Adam Carlsen. Destroyer of research careers , Olive had once overheard her adviser say.

It's okay. It's fine. Totally fine. She was just going to pretend nothing had happened, nod at him politely, and tiptoe her way out of here. Yes, solid plan.

"Did you . . . Did you just kiss me?" He sounded puzzled, and maybe a little out of breath. His lips were full and plump and . . . God. Kissed. There was simply no way Olive could get away with denying what she had just done.

Still, it was worth a try.

Surprisingly, it seemed to work.

"Ah. Okay, then." Carlsen nodded and turned around, looking vaguely disoriented. He took a couple of steps down the hallway, reached the water fountain-maybe where he'd been headed in the first place.

Olive was starting to believe that she might actually be off the hook when he halted and turned back with a skeptical expression.

"Are you sure?"

"I-" She buried her face in her hands. "It's not the way it looks."

"Okay. I . . . Okay," he repeated slowly. His voice was deep and low and sounded a lot like he was on his way to get ting mad. Like maybe he was already mad. "What's going on here?"

There was simply no way to explain this. Any normal person would have found Olive's situation odd, but Adam Carlsen, who obviously considered empathy a bug and not a feature of humanity, could never understand. She let her hands fall to her sides and took a deep breath.

"I . . . listen, I don't mean to be rude, but this is really none of your business."

He stared at her for a moment, and then he nodded. "Yes. Of course." He must be getting back into his usual groove, because his tone had lost some of its surprise and was back to normal-dry. Laconic. "I'll just go back to my office and begin to work on my Title IX complaint."

Olive exhaled in relief. "Yeah. That would be great, since- Wait. Your what?"

He cocked his head. "Title IX is a federal law that protects against sexual misconduct within academic settings-"

"I know what Title IX is."

"I see. So you willfully chose to disregard it."

"I- What? No. No, I didn't!"

He shrugged. "I must be mistaken, then. Someone else must have assaulted me."

"Assault-I didn't 'assault' you."

"You did kiss me."

"But not really ."

"Without first securing my consent."

"I asked if I could kiss you!"

"And then did so without waiting for my response."

"What? You said yes."

"Excuse me?"

She frowned. "I asked if I could kiss you, and you said yes."

"Incorrect. You asked if you could kiss me and I snorted."

"I'm pretty sure I heard you said yes."

He lifted one eyebrow, and for a minute Olive let herself daydream of drowning someone. Dr. Carlsen. Herself. Both sounded like great options.

"Listen, I'm really sorry. It was a weird situation. Can we just forget that this happened?"

He studied her for a long moment, his angular face serious and something else, something that she couldn't quite decipher because she was too busy noticing all over again how damn towering and broad he was. Just massive. Olive had always been slight, just this side of too slender, but girls who are five eight rarely felt diminutive. At least until they found themselves standing next to Adam Carlsen. She'd known that he was tall, of course, from seeing him around the department or walking across campus, from sharing the elevator with him, but they'd never interacted. Never been this close.

Except for a second ago, Olive. When you almost put your tongue in his-

"Is something wrong?" He sounded almost concerned.

"What? No. No, there isn't."

"Because," he continued calmly, "kissing a stranger at midnight in a science lab might be a sign that there is."

"There isn't."

Carlsen nodded, thoughtful. "Very well. Expect mail in the next few days, then." He began to walk past her, and she turned to yell after him.

"You didn't even ask my name!"

"I'm sure anyone could figure it out, since you must have swiped your badge to get in the labs area after hours. Have a good night."

"Wait!" She leaned forward and stopped him with a hand on his wrist. He paused immediately, even though it was obvious that it would take him no effort to free himself, and stared pointedly at the spot where her fingers had wrapped around his skin-right below a wristwatch that probably cost half her yearly graduate salary. Or all of it.

She let go of him at once and took one step back. "Sorry, I didn't mean to-"

"The kiss. Explain."

Olive bit into her lower lip. She had truly screwed herself over. She had to tell him, now. "Anh Pham." She looked around to make sure Anh was really gone. "The girl who was passing by. She's a graduate student in the biology department."

Carlsen gave no indication of knowing who Anh was.

"Anh has . . ." Olive pushed a strand of brown hair behind her ear. This was where the story became embarrassing. Complicated, and a little juvenile sounding. "I was seeing this guy in the department. Jeremy Langley, he has red hair and works with Dr. . . . Anyway, we went out just a couple of times, and then I brought him to Anh's birthday party, and they just sort of hit it off and-"

Olive shut her eyes. Which was probably a bad idea, because now she could see it painted on her lids, how her best friend and her date had bantered in that bowling alley, as if they'd known each other their whole lives; the never-exhausted topics of conversation, the laughter, and then, at the end of the night, Jeremy following Anh's every move with his gaze. It had been painfully clear who he was interested in. Olive waved a hand and tried for a smile.

"Long story short, after Jeremy and I ended things he asked Anh out. She said no because of . . . girl code and all that, but I can tell that she really likes him. She's afraid to hurt my feelings, and no matter how many times I told her it was fine she wouldn't believe me."

Not to mention that the other day I overheard her confess to our friend Malcolm that she thought Jeremy was awesome, but she could never betray me by going out with him, and she sounded so dejected. Disappointed and insecure, not at all like the spunky, larger-than-life Anh I am used to.

"So I just lied and told her that I was already dating someone else. Because she's one of my closest friends and I'd never seen her like a guy this much and I want her to have the good things she deserves and I'm positive that she would do the same for me and-" Olive realized that she was rambling and that Carlsen couldn't have cared less. She stopped and swallowed, even though her mouth felt dry. "Tonight. I told her I'd be on a date tonight ."

"Ah." His expression was unreadable.

"But I'm not. So I decided to come in to work on an experiment, but Anh showed up, too. She wasn't supposed to be here. But she was. Coming this way. And I panicked-well." Olive wiped a hand down her face. "I didn't really think."

Carlsen didn't say anything, but it was there in his eyes that he was thinking. Obviously.

"I just needed her to believe that I was on a date."

He nodded. "So you kissed the first person you saw in the hallway. Perfectly logical."

Olive winced. "When you put it like that, perhaps it wasn't my best moment."

"But it wasn't my worst, either! I'm pretty sure Anh saw us. Now she'll think that I was on a date with you and she'll hopefully feel free to go out with Jeremy and-" She shook her head. "Listen. I'm so, so sorry about the kiss."

"Please, don't report me. I really thought I heard you say yes. I promise I didn't mean to . . ."

Suddenly, the enormity of what she had just done fully dawned on her. She had just kissed a random guy, a guy who happened to be the most notoriously unpleasant faculty member in the biology department. She'd misunderstood a snort for consent, she'd basically attacked him in the hallway, and now he was staring at her in that odd, pensive way, so large and focused and close to her, and . . .

Maybe it was the late night. Maybe it was that her last coffee had been sixteen hours ago. Maybe it was Adam Carlsen looking down at her, like that. All of a sudden, this entire situation was just too much.

"Actually, you're absolutely right. And I am so sorry. If you felt in any way harassed by me, you really should report me, because it's only fair. It was a horrible thing to do, though I really didn't want to . . . Not that my intentions matter; it's more like your perception of . . ."

Crap, crap, crap.

"I'm going to leave now, okay? Thank you, and . . . I am so, so, so sorry." Olive spun around on her heels and ran away down the hallway.

"Olive," she heard him call after her. "Olive, wait-"

She didn't stop. She sprinted down the stairs to the first floor and then out the building and across the pathways of the sparsely lit Stanford campus, running past a girl walking her dog and a group of students laughing in front of the library. She continued until she was standing in front of her apartment's door, stopping only to unlock it, making a beeline for her room in the hope of avoiding her roommate and whoever he might have brought home tonight. It wasn’t until she slumped on her bed, staring at the glow‑in‑the- dark stars glued to her ceiling, that she realized that she had neglected to check on her lab mice. She had also left her laptop on her bench and her sweatshirt somewhere in the lab, and she had completely forgotten to stop at the store and buy the coffee she’d promised Malcolm she’d get for tomorrow morning. Shit. What a disaster of a day. It never occurred to Olive that Dr. Adam Carlsen— known ass— had called her by her name.

About the author

Ali hazelwood.

Ali Hazelwood is a multi-published author—alas, of peer-reviewed articles about brain science, in which no one makes out and the ever after is not always happy. Originally from Italy, she lived in Germany and Japan before moving to the U.S. to pursue a Ph.D. in neuroscience. She recently became a professor, which absolutely terrifies her. When Ali is not at work, she can be found running, crocheting, eating cake pops, or watching sci-fi movies with her two feline overlords (and her slightly-less-feline husband).

After a fake relationship generates real sparks, a rising scientist must decide if she's ready to experiment with love.

Good to know

As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships—but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor—and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding... six-pack abs.

Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

Free sample

Frankly, Olive was a bit on the fence about this whole grad school thing.

Not because she didn’t like science. (She did. She loved science. Science was her thing .) And not because of the truckload of obvious red flags. She was well aware that committing to years of unappreciated, underpaid eighty-?­hour workweeks might not be good for her mental health. That nights spent toiling away in front of a Bunsen burner to uncover a trivial slice of knowledge might not be the key to happiness. That devoting her mind and body to academic pursuits with only infrequent breaks to steal unattended bagels might not be a wise choice.

She was well aware, and yet none of it worried her. Or maybe it did, a tiny bit, but she could deal. It was something else that held her back from surrendering herself to the most notorious and soul-?­sucking circle of hell (i.e., a Ph.D. program). Held her back, that is, until she was invited to interview for a spot in Stanford’s biology department, and came across The Guy.

The Guy whose name she never really got.

Why I love it

Rachael Burlette

Botm editorial team.

What is the formula for a perfect romance? For me, it’s about the sweet moments, the witty banter, and amazing chemistry. I’m particularly drawn to love stories that also go beyond falling in love, which is why I was excited to read about Olive’s journey as a young scientist. I loved her drive and ambition. Once I began reading The Love Hypothesis , I knew that it had all the right elements to become one of my new favorite romances.

Set in the world of academia, Olive is a Ph.D. biology student who spends most of her time in a lab. She certainly doesn’t have time for dating. So when she kisses a random person at her university to convince her best friend, Anh, that she is doing just fine, she finds herself entering into a fake dating agreement with the infamously grumpy Professor Carlsen. It’s the perfect plan: Olive’s friends will stop worrying about her and Adam’s bosses will believe he’s not leaving for a new job anytime soon. Adam and Olive just need to follow a few ground rules and not fall in love. What could possibly go wrong?

On the surface, this book is a fun romance about a hilarious fake dating scheme. But it’s also more than that. It’s a glimpse into the world of academia and the obstacles women face in the male-dominated STEM field. I found myself reading this book whenever I had the chance. I felt completely invested in Adam and Olive’s love story and how everything would unfold. The Love Hypothesis is everything that you’ll want in your next read. I have a theory you’ll love this book—I know I did!

THE LOVE HYPOTHESIS

by Ali Hazelwood ‧ RELEASE DATE: Sept. 14, 2021

Fresh and upbeat, though not without flaws.

An earnest grad student and a faculty member with a bit of a jerkish reputation concoct a fake dating scheme in this nerdy, STEM-filled contemporary romance.

Olive Smith and professor Adam Carlsen first met in the bathroom of Adam's lab. Olive wore expired contact lenses, reducing her eyes to temporary tears, while Adam just needed to dispose of a solution. It's a memory that only one of them has held onto. Now, nearly three years later, Olive is fully committed to her research in pancreatic cancer at Stanford University's biology department. As a faculty member, Adam's reputation precedes him, since he's made many students cry or drop their programs entirely with his bluntness. When Olive needs her best friend, Anh, to think she's dating someone so Anh will feel more comfortable getting involved with Olive's barely-an-ex, Jeremy, she impulsively kisses Adam, who happens to be standing there when Anh walks by. But rumors start to spread, and the one-time kiss morphs into a fake relationship, especially as Adam sees there's a benefit for him. The university is withholding funds for Adam's research out of fear that he'll leave for a better position elsewhere. If he puts down more roots by getting involved with someone, his research funds could be released at the next budgeting meeting in about a month's time. After setting a few ground rules, Adam and Olive agree that come the end of September, they'll part ways, having gotten what they need from their arrangement. Hazelwood has a keen understanding of romance tropes and puts them to good use—in addition to fake dating, Olive and Adam are an opposites-attract pairing with their sunny and grumpy personalities—but there are a couple of weaknesses in this debut novel. Hazelwood manages to sidestep a lot of the complicated power dynamics of a student-faculty romance by putting Olive and Adam in different departments, but the impetus for their fake relationship has much higher stakes for Adam. Olive does reap the benefits of dating a faculty member, but in the end, she's still the one seemingly punished or taunted by her colleagues; readers may have been hoping for a more subversive twist. For a first novel, there's plenty of shine here, with clear signs that Hazelwood feels completely comfortable with happily-ever-afters.

PERSPECTIVES

by Ali Hazelwood ‧ RELEASE DATE: Feb. 6, 2024

Sink your teeth into this delightful paranormal romance with a modern twist.

A vampire and an Alpha werewolf enter into a marriage of convenience in order to ease tensions between their species.

As the only daughter of a prominent Vampyre councilman, Misery Lark has grown accustomed to having to playing the role that’s demanded of her—and now, her father is ordering her to be a part of yet another truce agreement. In an effort to maintain goodwill between the Vampyres and their longtime nemeses the Weres, Misery must wed their Alpha, Lowe Moreland. But it turns out that Misery has her own motivations for agreeing to this political marriage, including finding answers about what happened to her best friend, who went missing after setting up a meeting in Were territory. Isolated from her kind and surrounded on all sides by the enemy after the wedding, Misery refuses to let herself forget about her real mission. It doesn’t matter that Lowe is one of the most confounding and intense people she’s ever met, or that the connection building between them doesn’t feel like one born entirely of convenience. There’s also the possibility that Lowe may already have a Were mate of his own, but in spite of their biological differences, they may turn out to be the missing piece in each other’s lives. While this is Hazelwood’s first paranormal romance, and the book does lean on some hallmark tropes of the genre, the contemporary setting lends itself to the author’s trademark humor and makes the political plot more easily digestible. Misery and Lowe’s slow-burn romance is appealing enough that readers will readily devour every moment between them and hunger to return to them whenever the story diverts from their scenes together.

IT ENDS WITH US

by Colleen Hoover ‧ RELEASE DATE: Aug. 2, 2016

Packed with riveting drama and painful truths, this book powerfully illustrates the devastation of abuse—and the strength of...

Hoover’s ( November 9 , 2015, etc.) latest tackles the difficult subject of domestic violence with romantic tenderness and emotional heft.

At first glance, the couple is edgy but cute: Lily Bloom runs a flower shop for people who hate flowers; Ryle Kincaid is a surgeon who says he never wants to get married or have kids. They meet on a rooftop in Boston on the night Ryle loses a patient and Lily attends her abusive father’s funeral. The provocative opening takes a dark turn when Lily receives a warning about Ryle’s intentions from his sister, who becomes Lily’s employee and close friend. Lily swears she’ll never end up in another abusive home, but when Ryle starts to show all the same warning signs that her mother ignored, Lily learns just how hard it is to say goodbye. When Ryle is not in the throes of a jealous rage, his redeeming qualities return, and Lily can justify his behavior: “I think we needed what happened on the stairwell to happen so that I would know his past and we’d be able to work on it together,” she tells herself. Lily marries Ryle hoping the good will outweigh the bad, and the mother-daughter dynamics evolve beautifully as Lily reflects on her childhood with fresh eyes. Diary entries fancifully addressed to TV host Ellen DeGeneres serve as flashbacks to Lily’s teenage years, when she met her first love, Atlas Corrigan, a homeless boy she found squatting in a neighbor’s house. When Atlas turns up in Boston, now a successful chef, he begs Lily to leave Ryle. Despite the better option right in front of her, an unexpected complication forces Lily to cut ties with Atlas, confront Ryle, and try to end the cycle of abuse before it’s too late. The relationships are portrayed with compassion and honesty, and the author’s note at the end that explains Hoover’s personal connection to the subject matter is a must-read.

The Love Hypothesis

Quick recap & summary by chapter.

The Quick Recap and Chapter-by-Chapter Summary for The Love Hypothesis by Ali Hazelwood are below.

Quick(-ish) Recap

Three years prior, Olive Smith talks to a guy when she's in the bathroom fixing her contacts (and can't see) after her Ph.D. candidate interview. She tells him about her passion for her research. She doesn't catch his name but remembers the conversation distinctly and wonders about the guy she met.

In present day, Olive is a biology Ph.D. student researching early detection methods for pancreatic cancer. She kisses a guy randomly in order to trick her best friend into thinking she's dating someone (so that her best friend Anh won't feel bad about dating Olive's ex). That guy turns out to be Dr. Adam Carlson , a young, handsome and highly-respected tenured faculty member in her department. He's also known for being hypercritical and moody.

Meanwhile, Adam's department chair is worried that he's planning on leaving for another university and has frozen some of his research funds. So, Adam he agrees to pretend to be in a relationship with Olive in order to give the impression he's putting down "roots" here, in hopes they will unfreeze the funds.

As Olive and Adam fake-date, they get to know each other. Olive sees that Adam is demanding and blunt towards his students, but not unkind or mean. Olive confides in him about her mother getting pancreatic cancer, which is why she's doing her research.

Olive soon realizes that she has feelings for Adam, but she's afraid to tell him. When he overhears her talking about a crush, she pretends it's about someone else. Olive also hears someone else refer to a woman Adam's been pining after for years and is surprised at how jealous she feels.

In the meantime, Olive needs more lab space and has been talking to Dr. Tom Benton for a spot at his lab at Harvard. When Tom arrives in town, it turns out he's friends with Adam. Adam and Tom are friends from grad school, and they have recently gotten a large grant for some joint research that Adam is excited about. After Olive completes a report on her research for Tom, he offers her a spot in his lab for the next year.

Olive and Adam's relationship continues to progress until they attend a science conference in Boston. Olive's research has been selected for a panel presentation, while Adam is a keynote speaker. There, Olive is sexually harassed by Tom, who makes advances on her. When she rejects him, he accuses her of someone who sleeps around to get ahead. He also says that he'll deny it if she tells anyone and that they won't believe her.

While Olive does finally sleep with Adam at the conference, she soon tearfully breaks things off since she doesn't want to complicate things with Adam's joint research project with Tom. Adam is also in the process of applying for a spot at Harvard.

Olive is certain no one will believe her about Tom until she realizes that the accidentally recorded the conversation where he made advances and threatened her. Meanwhile, Olive's roommate Malcolm has started seeing Dr. Holden Rodriguez, a faculty member who is a childhood friend of Adam's. Olive and Malcolm turn to Holden for advice, who encourages them to tell Adam about the recording. He points out that he thinks the main reason that Adam is considering a move to Harvard is because Olive is supposed to be going there.

Olive finds Adam and shows him the video. He is incensed at Tom and reports it to their faculty. When Adam returns from Boston, he reports that Tom has been fired. Meanwhile, Olive has been reaching out to other cancer researchers for spots at other labs, and she's gotten promising responses. Olive tells Adam that she loves him and that she never liked anyone else. Adam admits that he remembered her from the day he met her in the bathroom and that she's the one he's been interested in for years.

Ten months later at the anniversary of their first kiss, Olive and Adam re-create the kiss to mark their anniversary.

Chapter-by-Chapter Summary

Olive Smith is an applicant for Stanford’s biology Ph.D program. After the interview with Dr. Aysegul Aslan , she ends up in a bathroom nearby unable to see and trying to wash out her eyes because she put in expired contacts.

She meets “The Guy” there, who she assumes is a Ph.D student there. As they strike up a conversation, she tells him that her name is Olive and talks about why she’s applying to the program. She tells him that she wants to do it in order to research a specific topic.

A few weeks later, Olive is accepted into the program.

Years later, Olive is now 26 and a Ph.D. student in Dr. Aslan’s lab. Olive has just kissed a random stranger (in order to trick her best friend, Anh , into thinking she’s on a date) — only to realize that the “stranger” is actually Dr. Adam Carlson , a 34-year-old tenured and highly-respected professor in her program with a reputation for being notorious moody, mean and hypercritical.

After they pull away, Adam accuses her of assaulting him. Olive insists she asked him and he said yes, but he says he merely snorted. Finally, she explains that her friend Anh had hit it off with a guy she’d been dating, Jeremy. Olive broke things off with Jeremy, but Anh felt too bad to go out with Jeremy. To make Anh feel better about it, Olive lied to Anh about dating someone and being on a date tonight. When Anh showed up at the lab, Olive needed to kiss someone so Anh would believe she was on a date.

Finally, Olive apologizes and leaves. She doesn’t notice that Adam had called her by her name (which she hadn’t brought up in this conversation).

A few days later, Olive is still embarrassed by what happened. However, she figures that she’d never crossed paths with Adam before then, so perhaps she wouldn’t cross paths with him again. Meanwhile, Olive is preoccupied with needing to find more lab space for her research on early detection of pancreatic cancer. Today, she also finds out Tom Benton , a well-known cancer researcher and an associate professor at Harvard, is interested in potentially allowing her to carry out her research at his lab at Harvard. He’s going to be in town in two weeks and wants to meet with her.

When Anh sees her, she confronts Olive about kissing Adam Carlson. Olive thinks back to how they met since they were the only two non-cis-white-male students in their class. Beyond that, Anh was her biggest support and best friend.

Today, Anh demands to know why Olive is dating Dr. Carlson. This conversation is interrupted when Adam walks in. He plays along and pretends that he and Olive are together. After they make formal introductions, he tells her to call him Adam, in case her friend Anh is around. Later, when Olive talks to Anh again, Olive continues to pretend she’s dating Adam, and she once again encourages Anh to date Jeremy.

On campus, Olive starts to notice that people are treating her differently and with some level of curiosity. When her roommate, Malcom , demands to know why she didn’t tell him about dating Dr. Carlson, Olive realize that everyone know about her lie. Olive goes to Adam’s lab to tell him what’s going on, and she apologizes to him for it.

Olive notes that he seems very at ease with everyone believing that they’re dating, and she wonders why. Finally, he admits that Stanford considers him to be a “flight risk” (that he wants to leave them for another institution) and that they’ve frozen some of his research funds because of it. Part of the issue is that he’s recently gotten a large grant with one of his collaborator’s at another institution, and the department is worried he’s planning on moving there. He hopes that the dating rumors will make them think he’s more likely to stick around since he’s dating someone here.

A few days later, Olive goes to Adam’s office and tells him she wants to proceed with pretending that they’re dating. Olive notices that she’s been treated much better by everyone since the rumor started. (Apart from Malcom, who dislikes Adam Carlson, and has been shunning her.) Adam explains that he’s looked into it and there’s no issue with it, though he can’t serve in any supervisory capacity for her or serve on her thesis committee or be a part of any decisions if she’s nominated for a fellowship or other awards.

They decide to set some ground rules for their fake-dating arrangement. They decide to be fake-dating while on-campus only, so no personal engagements. Olive stipulates that there’ll be no sex. They also agree not to date others in the interim, since it will make things messy. And they agree that they should get coffee or something regularly to make things believable.

They plan to continue their fake-dating until September 29, roughly a month from now, which is the day after the department’s budget review. Their first coffee “date” is planned for Wednesday at 10 AM.

Later, Olive talks to Malcom, who is still upset with her. Malcom comes from a long line of well-known scientists, and he dislikes that Adam Carlson’s criticism of his research had made his life so difficult. Olive confides in Malcom that they’re merely fake-dating and that she barely knows Adam. She says that he’s just helping her out with the Anh/Jeremy situation (and she doesn’t mention Adam’s reasons for participating).

On Wednesday, Olive and Adam have their first fake-date at the coffee house. They ask each other some basic questions, and Adam pays for her order.

The next week, they meet up again, though Olive is running late since she was getting ready for a meeting she has with Tom Benton later that day. Meanwhile, Adam is a little moody because his department chair has still not agreed to release his research funds. They discuss attending the fall biosciences picnic together so that his department chair can see that they’re together.

They’re interrupted when a friend of Adam’s walks in and greets him warmly. Adam introduces the man to Olive as his friend and collaborator — who turns out to be Tom Benton.

Dr. Benton reveals that he’s heard about Adam’s romantic exploits all the way at Harvard, and he’s surprised to hear the rumors about Adam’s new girlfriend being true. Olive also awkwardly tells Dr. Benton that they have a meeting planned for later that day. Tom is delighted to find out that his meeting is with Adam’s new girlfriend.

The three of them sit down to chat. As Tom asks her about her research, Adam rephrases it to help Olive organize her thoughts when he sees that she’s struggling to come up with an answer. Olive then tells Tom about her research on biomarkers in order to more easily and cheaply diagnose pancreatic cancer. As Tom inquires about her reasons for doing her research, Olive reluctantly admits that it’s because her mother had pancreatic cancer.

Finally, Tom asks Olive to spend two weeks writing up a report on the current state of her research. He says that he’ll make a determination of whether to give her the lab space and cover her research expenses depending on what he reads in that report.

When Tom steps away, Olive and Adam discuss that if she decides to go to Harvard then she needs to keep it a secret until the end of their arrangement, otherwise it’ll make Adam look worse. They also agree not to tell Tom that they’re only fake-dating.

The next day, Olive attends a well-attended talk that Tom is giving on campus. The auditorium is so packed that there’s no space anywhere. Anh convinces Olive to sit in Adam’s lap for the duration of the talk.

Afterwards, Olive and Anh head back to the biology building. Olive talks about the report she’s preparing for Tom and the presentation she needs to work on for a conference (the “SBD Conference”) coming up in Boston. Meanwhile, Anh is working on organizing an outreach event for BIPOC women in STEM for the conference.

As they walk back, they see that there’s a traffic jam involving a stopped car blocking an exit. Then they see Cherie , the department secretary, talking to Adam. Adam then proceeds to physically push a car out of the way to relieve the jam. Anh encourages Olive to go over and give him a kiss for his efforts. After some awkward negotiation with Adam, they kiss.

Olive is working on her report for Tom when Greg Cohen , one of Dr. Aslan’s other Ph.D. candidates, barges in, clearly agitated. Chase , another one of their lab mates, walks in uneasily after him. When Olive asks Greg what’s wrong, he angrily responds that Carlson is on his dissertation committee and he failed his proposal. They ask Olive whether she knew he was going to fail Greg, and Olive insists she didn’t know. Greg then yells at Olive and calls her selfish for not caring how Adam makes everyone’s lives miserable. Greg then storms off.

Later that day, Olive texts Adam. She asks him about failing Greg. She argues that he should be nicer, but Adam is unapologetic. He insists that his job is to make sure that students produce useful research. Olive gets frustrated texts profanity at him, and he doesn’t respond.

A few days later, Olive is on her way to the biosciences picnic, where she’ll be seeing Adam after their tense exchange. She, Anh, Jeremy and Malcom go together and are quite late. When they arrive, they see Adam playing Ultimate Frisbee shirtless, showing off his six-pack. Olive is surprised to find herself “viscerally attracted” to Adam.

As they put on sunscreen, Anh gives Olive way too much sunscreen. Meanwhile, the frisbee from the game lands near her. When Adam comes over to retrieve the frisbee, Anh offers Olive’s excess sunscreen to Adam. He accepts, and Olive rubs the sunscreen on him. Olive also apologizes for what she texted him the other day.

Tom then comes over and brings up that Adam will be going to Boston soon for a few days.

Olive is in the break room at night when she runs into Adam next. Olive is working on her report for Tom, but there’s a section she’s having trouble with since her lab equipment seems to be messing up. They chat and share snacks. Olive finds herself wondering why he’s single.

Olive also finds herself telling him about her mother and her death. She describes how, when she was 15, her mother was diagnosed with pancreatic cancer too late and only had a few weeks left to live by then. Olive also says that her father was never in the picture and her grandparents were deceased, so she was sent into the foster system until she was emancipated at 16.

When she mentions needing to get back to work, Adam offers to let her use his lab equipment if she needs it. He also gives her some advice on the Western blot she’s working with to make sure she’s doing it correctly. Before Olive leaves, she asks Adam why he’s single, but before he can really answer, Jeremy walks in and interrupts them.

On Saturday, Olive sends in her report to Tom. He responds by asking her to meet to talk about it at Adam’s house (where he’s staying) on Tuesday before he leaves for Boston. At Adam’s house, she and Tom chat about her report for about 20 minutes. Before she leaves, Tom offers her a spot at Harvard for the next year, and Olive is thrilled.

Adam gives her a ride back to campus. He talks about how excited he is about the research he and Tom are working on. As they chat, Adam says something that The Guy she’d met in the bathroom all those years ago had said to her. Olive realizes then that Adam was The Guy she’d met. She marvels at how she’d wondered about The Guy for years. Olive then suggests that go celebrate her lab spot and him and Tom’s grant.

They agree to get coffee. Before then, she convinces him to go with her to get flu shots at the setup on campus, all the while she teases him for his fear of needles.

On Wednesday, Olive and Adam are texting and teasing each other when Anh comes in and comments on how in love with Adam she is. Anh says that she feels better about dating Jeremy, since she sees how much Olive likes Adam. As Anh leaves, it dawns on Olive that Anh is right.

Olive soon texts Malcolm asking to talk. When they get together, she tells him about how she thinks she’s fallen for Adam. She also tells him that she thinks that Adam was The Guy that she met all those years ago. Malcolm suggests that perhaps Adam feels the same way. Olive doesn’t think that’s the case, but moreover, she says scared of being vulnerable and possibly giving up the friendship she and Adam currently have if she’s wrong. Olive also says that everyone she cares about ends up leaving her — citing her mother, father and grandparents.

Olive says she’s certain she doesn’t want to say anything to Adam about her feelings — but then she turns around and sees Adam standing there.

When Adam acknowledges that he overheard her, Olive quickly lies and said she was talking about some other guy she has a crush on. Their conversation is interrupted by Dr. Holden Rodriguez , who is going to Boston with Tom and Adam. Dr. Rodriguez knows Olive since he was on her graduate advisory committee her first year.

As they talk, Holden explains that he and Adam are old friends. They grew up together because their parents were all diplomats. Holden tells Olive about how his boyfriend dumped him just before prom, so Adam went as his date instead.

After Holden leaves, Adam comments that Holden speaks highly of Olive and her research. Adam also explains a comment Holden made about Tom, saying that the two don’t really get along. He then tells Olive that she should just tell Jeremy how she feels, incorrectly assuming that the mystery crush Olive was referring to is Jeremy.

Malcolm continues trying to convince Olive to admit her feelings to Adam, but Olive refuses. With Adam out of town, she feels his absence. When Adam finally texts her on Sunday, she feels even worse about her stupid lie about liking someone else.

On campus, she runs into Holden, who mentions how glad he is that Adam and Olive got together. Holden days that Adam had talked about someone he wanted to ask out for years, and he’s glad Adam finally did it. When he says that, Olive thinks about how there must be someone else out there that Adam likes, then, since they only really met a couple weeks ago.

Holden also warns her to watch out when it comes to Tom and to watch Adam’s back, since he doesn’t trust Tom.

A little later, Olive is informed that her research has been accepted for the SBD conference as a panel presentation with faculty. Olive feels overwhelmed, since graduate students very rarely are selected for oral presentations. She goes to her advisor, Dr. Aslan, and explains that she’s terrible at talking. Of course, Dr. Aslan just gives her some encouragement and tells Olive she’ll help her practice her presentation.

Afterwards, Olive tells Malcom and Anh, who also volunteer to help her practice. They also mention, however, that they each got invited to stay with people in Boston for the conference (Anh with Jeremy and Malcolm with some friends who had a spare room), so they won’t be rooming with Olive. Anh says she figured Olive would stay with Adam.

Olive is trying to sort out some living arrangements for Boston when Adam, who is back in town now, comes up to her. She tells him about having trouble finding accommodations in Boston. Adam comments that there’s probably not anything left in the vicinity by now, but she could stay in his room at the conference center. He adds that he has the room for the whole conference, but he will only be using the room two nights, so they’ll only overlap for one night most likely.

When she tells him about her presentation, he offers to look over her slides. She also invites him to her talk, and she thinks about how one of the reasons she likes him is that she always feels like he’s on her side.

At the hotel in Boston, Olive takes the empty bed, and she rehearses the talk she’s about to give in a few hours. When Adam arrives, she thanks him for all the help he gave regarding her presentation.

He asks when her presentation is so he can attend, but it turns out it overlaps with the Keynote speech, which he is giving along with two other people. She offers to show him the recording of it afterwards.

When Olive goes to do her panel presentation, she sees that Tom is on the same panel. She gives her portion of the talk, and it goes well. Malcolm and Anh are there to cheer her on.

Afterwards, the room empties out, and it’s just her and Tom. As they talk, she notices him moving closer until he tries to kiss her. When she pushes him away, he keeps trying. Finally, he says that she’s clearly someone who sleeps around to get ahead, and so they both know she’ll sleep with him, too, for the same reason. He also says that she only got on this panel because someone wanted to kiss-up to Adam Carlson.

He also says that Adam is the reason he accepted Olive into his lab. When Olive threatens to tell Adam about this, he says that Adam won’t believe her word against his. Olive also says she won’t go work in his lab, but Tom says she knows it’s the best option for her, and if she doesn’t then he’ll just replicate her research since he already knows all about it.

When Adam gets back to the hotel, Olive is crying. She tries to pretend nothing is wrong, but fails at it. Finally, she lies and tells him that she’s upset because she overheard someone saying that her research was “derivative” and that she was only chosen because of Adam.

Adam comforts her, and then he says he has an idea for where they should go instead.

Holding her hand, they walk past all the people at the department social and instead head out to dinner. Adam asks what she wants to eat, and Olive sees an all-you-can-eat sushi place and wants to go.

After dinner, as they head back, Olive’s heels are hurting her, so Adam gamely picks her up and brings her to their room. She then suggests that they watch a movie. Olive goes to grab a quick shower, and Adam offers her a t-shirt since she forgot to pack pajamas.

When Olive’s mind wanders back to being called mediocre (by Tom, though she doesn’t tell Adam that), Adam tells her about how his advisor had once told him he wouldn’t amount to anything because of a mistake he made. He says that he had started preparing applications for law school as a result, since the comment shook his confidence. However, Holden and Tom (who also trained under the same advisor) convinced him to stick with science.

Adam says that later he realized that his advisor was abusive and a bad mentor who created a toxic environment. Comparatively, Adam says that he is critical since he wants students to be better, but it isn’t about belittling them as people or cutting down their self-worth. Adam also says that no one ever reported his advisor’s behavior because he was short-listed for a Nobel Prize, and they didn’t think anyone would listen. Adam also mentions how Tom had helped mediate thing with him and his advisor, so he was grateful to Tom for that.

Adam then tells Olive that the abstracts submitted to SBD go through a blind review process, so they definitely didn’t choose her because of him.

Finally, Olive moves to kiss Adam, but before anything can happen, he stops her. He points out that she’s upset and staying in his room and that the situation feels coercive to him. When Olive says she’s fine, he points out that she said she was in love with someone else and that he doesn’t want to regret this later.

Olive convinces him that she’s fine with the situation, and soon things get intimate.

They have sex.

Afterwards, Olive asks Adam about a book he’s reading. He says it’s in Dutch and that he learned it as a kid. He also says that his parents were busy all the time and that he was mostly raised by au pairs. They then talk more about their childhoods.

As they chat, Adam finally tells Olive that he might be going to Harvard. The reason he’s leaving the conference early is to go interview with them. He thinks that working together with Tom in the same lab would make them much more productive. He also mentions that he could show her around Boston when she’s there.

Olive wakes up to a barrage of texts from Anh and Malcolm. When she finally talks to them, it turns out the Malcolm hooked up with Holden at the department social. Malcolm also says that Holden mentioned that Adam’s funds had been released (though Adam hadn’t mentioned it to Olive).

That night, Olive meets up with Adam. He wants to go out and have dinner, but Olive breaks things off with him, since she doesn’t know what to do about the Tom situation. She thinks that taking herself out of the equation is the best thing for him.

As she starts to leave, they end up kissing, but he pulls away, and she leaves.

Olive spends the next day crying. Then, determined not to send up at Harvard, Olive takes Adam’s advice to reach out to people through her advisor and asks Dr. Aslan to e-mail various people she’d met at the conference to see if they’d be interested in her research.

Dr. Aslan agrees, and also asks to see her speech. As Olive edits the video recording, Malcolm talks about how he went on a first date with Holden, but they ended up running into his entire family (since they are all science junkies who attend science conferences).

As she’s editing, Olive realizes she recorded her upsetting conversation with Tom. Malcolm and Anh hear her listening to it. Once they’ve listened to the whole thing, they insist that Olive needs to tell Adam about it. Finally, Malcolm fills Anh in on what was really going on with Olive and Adam. However, they both agree it’s clear that Olive has feelings for Adam and that Adam would want to know about this. Still, Olive knows how important the collaboration with Tom is to Adam, and she is reluctant to complicate things for him.

They decide to call Holden to ask for advice. Olive asks Holden what he thinks about Adam moving to Boston and working with Tom. Holden says that he doesn’t trust Tom. He says he thinks there was a weird dynamic where Tom was secretly sabotaging Adam during grad school and then defending him. He thinks that Tom likes Adam’s loyalty towards him and having influence over him. Holden also tells them that he thinks Tom and Adam’s collaboration benefits Tom more than Adam. Finally, Holden implies that he thinks the only reason Adam is considering leaving Stanford is because Olive is going to Harvard.

Olive tracks down Adam’s location at a dinner with some Harvard people, including Tom. When he sees her, he gets up and asks what’s wrong. Tom comes over to try to get Adam to sit back down, but Adam insists on talking to Olive. Finally, Olive starts playing the video. Adam grows furious as he realizes what happened. He tells Tom that he’s going to kill him and goes after him, but Olive tells Adam that he’s not worth it.

As the Harvard people demand an explanation, Adam ignores them and kisses Olive. He then tells Olive to send him the recording immediately and then goes to talk to the Harvard people.

A few days later, Olive is back home, and Adam is on his way back to San Francisco. Meanwhile, Olive has received responses from four cancer researchers who are all interested in her research.

When Adam gets back, Holden insists on a double date. Adam reluctantly agrees. When they all sit down, they address the fact that Malcolm still has misgivings about Adam because of Adam’s harsh criticism of his work. Adam tells Malcolm that it wasn’t personal.

As they joke around about pumpkin spiced flavored foods, Holden mentions how Adam has liked Olive for years. Olive corrects him, saying they’ve only been dating for a few weeks, but Holden says that they met three years ago and that he’s liked Olive ever since. Olive then realizes that Adam was definitely the The Guy (from three years ago) and that he did remember her.

After dinner, Olive and Adam head home. Adam tells Olive that Harvard is going to fire Tom and that there will be other disciplinary actions. Olive then tells Adam that she remembered him, too, from all those years ago. But she didn’t piece it together until later, and she admits that she didn’t say anything once she figured it out.

Finally, she tells him that she loves him (in broken Dutch).

Ten months later, it’s the 1-year anniversary of their first kiss. Olive and Adam go to the lab and recreate and their kiss at precisely the same time as last year.

As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships--but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor--and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding...six-pack abs.

Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

For Chapter 16, I think it’s important to include the part where Olive comes out to Adam as demisexual. But other than that this is a great summary.

this book is so good i couldn’t put it down. the only i wish is it was both POVS i would of loved to see what adam was thinking during all of this or have his thoughts on when they met each other during the bathroom scene. and i would of loved to see him actually hurting tom for saying that stuff to olive.

Love, Theoretically

The many lives of theoretical physicist Elsie Hannaway have finally caught up with her. By day, she’s an adjunct professor, toiling away at grading labs and teaching thermodynamics in the hopes of landing tenure. By  other  day, Elsie makes up for her non-existent paycheck by offering her services as a fake girlfriend, tapping into her expertly honed people-pleasing skills to embody whichever version of herself the client needs.

Honestly, it’s a pretty sweet gig—until her carefully constructed Elsie-verse comes crashing down. Because Jack Smith, the annoyingly attractive and arrogant older brother of her favorite client, turns out to be the cold-hearted experimental physicist who ruined her mentor’s career and undermined the reputation of theorists everywhere. And he’s the same Jack Smith who rules over the physics department at MIT, standing right between Elsie and her dream job.

And sure, he caught her in his powerfully corded arms like a romance novel hero when she accidentally damseled in distress on her first day in the lab. But Levi made his feelings toward Bee very clear in grad school — archenemies work best employed in their own galaxies far, far away.

The Love Hypothesis

As a third-year Ph.D. candidate, Olive Smith doesn’t believe in lasting romantic relationships–but her best friend does, and that’s what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor–and well-known ass. Which is why Olive is positively floored when Stanford’s reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive’s career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding…six-pack abs.

Under One Roof

As an environmental engineer, Mara knows all about the delicate nature of ecosystems. They require balance. And leaving the thermostat alone. And not stealing someone else’s food. And other rules Liam, her detestable big-oil lawyer of a roommate, knows nothing about. Okay, sure,  technically  she’s the interloper. Liam was already entrenched in his aunt’s house like some glowering grumpy giant when Mara moved in, with his big muscles and kissable mouth just sitting there on the couch tempting respectable scientists to the dark side…but Helena was  her  mentor and Mara’s not about to move out and give up her inheritance without a fight.

Stuck With You

Logically, Sadie knows that civil engineers are supposed to  build  bridges. However, as a woman of STEM she also understands that variables can change, and when you are stuck for hours in a tiny New York elevator with the man who broke your heart, you earn the right to burn that brawny, blond bridge to the ground. Erik can apologize all he wants, but to quote her rebel leader—she’d just as soon kiss a Wookiee.

Hannah’s got a bad feeling about this. Not only has the NASA aerospace engineer found herself injured and stranded at a remote Arctic research station—but the one person willing to undertake the hazardous rescue mission is her longtime rival.

Ian has been many things to Hannah: the villain who tried to veto her expedition and ruin her career, the man who stars in her most deliciously lurid dreams…but he’s never played the hero. So why is he risking everything to be here? And why does his presence seem just as dangerous to her heart as the coming snowstorm?

This book is similar to The Love Hypothesis in that it also has a storyline about two people bought together by science…or fate.

The story follows a single mom, Jess Davis, who is a statistics whizz. Her father was never around and her mother disappeared when she was six, and her ex decided he didn’t want to be a father – so she’s not overly fond of relationships.

But then Jess learns about a new DNA-based matchmaking company, GeneticAlly, and she’s intrigued. Can she find her soulmate through DNA?

When her test shows an impossible 98 percent match with the company’s founder, Dr. River Peña, she’s even more intrigued.

Meghan Quinn is a USA Today bestselling author, and A Not So Meet Cute is one of my favorite pieces of hers.

The love hypothesis audible audiobook – unabridged.

Now see Adam pine for Olive in a special bonus chapter!

The Instant New York Times Best Seller and TikTok Sensation!

As seen on The View !

A BuzzFeed Best Summer Read of 2021

When a fake relationship between scientists meets the irresistible force of attraction, it throws one woman's carefully calculated theories on love into chaos.

As a third-year PhD candidate, Olive Smith doesn't believe in lasting romantic relationships—but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor—and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding...six-pack abs.

Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

The Love Hypothesis by Ali Hazelwood

Olive Smith is a Ph.D. student who does not believe in her ability to be in love. When her best friend develops a crush on someone she dated briefly, she decides to kiss the first man she sees in order to prove she is over him.

That one kiss happens to be with THE Adam Carlsen, an academic genius. The two decide to fake-date and what starts out as pretend, becomes something more- for Olive. I loved this fake dating, office romance novel and it has a well-earned spot on its list of the best romance novels of all time.

Books like The Love Hypothesis with Characters in STEM

The Kiss Quotient by Helen Hoang

I was not prepared for this book!  Reader beware that it is the Rosie Project with a sprinkle of Pretty Woman and a whole lot of 50 Shades. 

It is not offensive in the least but, I listened to this one, and let me say that I am very glad that my kids were not in the car.  I did not realize that some of the scenes would be graphic. 

It is a great romance with a neurodiverse main character named Stella who hires an escort to teach her about relationships and I loved it. This contemporary romance is definitely on its way to classic status and has a well-earned place on our list of books like The Love Hypothesis.

The Rosie Project by Graeme Simsion

You know how this book is going to end even before you start reading it.  However, that does not make the journey any less enjoyable.  I found it to be cute and endearing.

Don Tillman is autistic and, as he’s the narrator, we get to listen to every unfiltered thought he has in his quest to find a wife. He approaches this in a scientific way and was a perfect pick for books like The Love Hypothesis . Don is also a character who reminded me of another favorite. If you loved this book, you can find more like it on our list of Charming Books Like Eleanor Oliphant is Completely Fine .

A Brush With Love by Mazey Eddings

Harper is a dental student who has worked so hard over the past three years to get into the best oral surgery program in the country. She will not let anyone or anything stand in her way. Her determination and grit remind me of Olive and this book needs to be included on a list of Books Like The Love Hypothesis.

When Harper crashes into Dan, a first-year dental student, everything changes. Despite being determined to stay “just friends”, Harper is finding that harder every day.

I enjoyed this pick from our list of romance books. There are detailed descriptions of Harper’s anxiety which at times is completely debilitating. I liked the fact that this book looks at anxiety and depression as a part of these characters without glossing over the realities.

Get a Life, Chloe Brown by Talia Hibbert

This was a book that I totally enjoyed.  I read reviews that people didn’t like Chloe.  They thought she was whiny and annoying.  I completely disagree. 

I thought that she was funny, quirky, and had more depth than I initially thought.  It is a well-written romance with a little more story than I usually find in this genre and for this reason

The Love Proof by Madeleine Henry

⁣Is there a formula that can prove love exists? Madeleine Henry does such a great job of mixing love with a drop of science to create this love story that spans decades. ⁣Sophie Jones is a physics prodigy exploring time.

During her first week at Yale she meets Jake Kristopher and the two immediately start a romance. But when the romance starts pulling Sophie from school, their relationship is tested. ⁣

⁣Sophie throws herself into her work to prove what she has always known (I won’t spoil this adorable read but it’s perfect for a list of books similar to The Love Hypothesis ). I wish the book was a little bit longer because I want to know more.

Work Romances Books Like The Love Hypothesis

Book Lovers by Emily Henry

As soon as I saw what this book was about, I knew I wanted to read it. I love Emily Henry books. Nora is a literary agent who is a shark for her clients. Her life is books and will stop and nothing for her job or her little sister, Libby.

When Libby begs Nora to take her to Sunshine Falls, the setting of one of her most famous books, she reluctantly agrees. When they get there, the town does not look anything like the book describes. In addition, her literary nemesis, book editor Charlie Lastra is in Sunshine Falls.

Now, Nora and Charlie find themselves together in a plot twist neither of them could see coming. This amazing romance about books is perfect for our list of Books Like The Love Hypothesis and is a must-read if you loved the book.

The Ex-Talk by Rachel Lynn Solomon

I picked up The Ex-Talk because I wanted to read a romance by a Jewish author . I loved that this one featured a biracial, interfaith couple.

The concept was cute – two radio show hosts fake a relationship to try to get ratings. Except they are pretending they already dated and broke up… which eventually leads to them dating.

This fake dating book was a cute, easy read. This is an office romance novel that is perfect for books like The Love Hypothesis.

Red, White & Royal Blue by Casey McQuiston

We don’t think about royals and the LGBTQ community because we don’t usually see openly gay royals, which is so sad in today’s society. And to think it all starts with a NYE kiss!

This charming book is a fabulous pick from LGBTQ romance novels. I crushed hard for their romance and found myself smiling the entire time. (Also love the nod to a female president…where do I sign up for one of those?)

Bringing Down the Duke by Evie Dunmore

Evie Dunmore’s debut novel spanned a series of badass women during the Suffragette era. While the story is a romance, don’t let that fool you!

Annabelle Archer has the scholarship to be one of the first women to study at Oxford. In order to keep it, she must spy on the Duke of Montgomery and try to persuade him to the suffragette’s cause. The chemistry between these two crackled off the page in this romance. If enemies-to-lovers books are up your alley, this book is perfect for you and it is perfect for a list of books like The Love hypothesis.

For the last two years, I have been emotionally dependent on romance books to take me away from the reality of the pandemic. Every time I think that things are looking up, I am thrown for a loop.

Suddenly, Tara finds herself in a dare to date the gorgeous and tempting Seth Kim without falling in love. This book was everything that I hoped it would be and is perfect if you loved the love hypothesis book.

Lessons in Chemistry by Bonnie Garmus

April 2022 gma book club pick.

I don’t even know where to begin with this unique contemporary fiction story. Elizabeth Zott is a chemist in the 50s when women were expected to know their place in society — their place being the kitchen and the home.

Elizabeth struggles to be taken seriously in her field and as a single mother, in this amazing book. So when an offer to host a cooking show for women is put in her path, she reluctantly takes it.

She uses her no-nonsense attitude and chemistry principles to teach the women in America to not only cook but to follow their dreams outside of the home.

Zott is a quirky character like Eleanor Oliphant with a charming daughter and a dog whose inner monologue is as quirky as hers. An absolutely wonderful book about motherhood! You can also find this book on our list of Books Like The Love Hypothesis as well.
