About the author, excerpt. © reprinted by permission. all rights reserved..

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).

  • " 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.

Insider Today

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.

love hypothesis book preview

"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.

Unexpectedly, Olive, usually quite perceptive, didn’t anticipate kissing not just any stranger, but a professor. What surprises her even more is when Adam Carlsen agrees to pretend to date her, but it becomes apparent he also has ulterior motives, realizing a genuine relationship could serve his own ends within the university community.

As Olive and Adam’s interactions fuel more speculation and gossip about their relationship, they find themselves slipping into a fake dating scenario, each with their own reasons for doing so. As the facade of their fake relationship begins to blur the lines of reality, Olive and Adam find themselves grappling with unexpected emotions. The gradual realization dawns on them both that what started as a charade has evolved into something genuine. The question looms: how long will it take for them to acknowledge their true feelings and abandon the pretense they’ve been upholding?

Did we love the overall storyline

From the very first chapter, I was hooked. The pull was undeniable, filled with glamour, sensuality, and an intoxicating charm! As a huge fan of the fake dating storyline, I found this book incredibly enjoyable. It offers not only lighthearted fun but also a depth of emotional vibrancy.

Featuring a brooding male lead, a quirky female protagonist, and a narrative blending science with contemporary romance. The story unfolded through witty banter over drinks, heated arguments via text and casual conversations in the lab break room. Through these encounters, Olive finds herself growing closer to Adam than she ever thought possible. The storyline is captivating, blending elements of romance and humor smoothly, making it impossible to put the book down.

Editor’s Remark

While immersed in its pages, I experienced a whirlwind of emotions, from hearty laughter to the occasional tear shed, as the characters’ personalities resonated deeply with me. Have you ever read a novel and wished it would never end? That was exactly how I felt about “The Love Hypothesis.” I found myself completely engrossed, wishing the story could continue indefinitely.

In general, “The Love Hypothesis” delivers a delightful reading experience that will leave you smiling and feeling butterflies in your stomach.

The book is just so entertaining that I highly recommend it to anyone looking for a charming romantic escape! You can get yourself a copy of this amazing book from Amazon .

APPLE BOOKS REVIEW

This adorkable fake-dating romance set in the world of academia might just be one of our favorite reads of the year. Biologist Olive Smith is too busy with the third year of her PhD program to worry about romance, so she’s fine when her ex and her best friend hook up. They feel guilty about it, though, and determined to see her best friend happy, Olive enters into a fake relationship with campus grump Dr. Adam Carlsen to prove just how over her ex she is. Little does Olive know that the curmudgeonly Adam has been secretly pining for her. Ali Hazelwood’s book is full of delightful tropes and a great sense of humor. The opposites-attract chemistry between stoic Adam and sunshiny Olive left us grinning from ear to ear.

PUBLISHERS WEEKLY JUN 7, 2021

Hazelwood debuts with a charming, offbeat rom-com pairing a somewhat awkward doctoral candidate with a hotshot young professor. Olive Smith, a third-year PhD student in biology at Stanford University, doubts that happily ever after exists, while her bestie, Anh, is a hopeless romantic. But Olive briefly dated Anh's current crush, Jeremy, and now Anh's refusing to act on her feelings because of "girl code." In an attempt to prove she's over Jeremy and alleviate Anh's guilt, Olive impulsively kisses famously irascible professor Adam Carlsen and convinces him to "fake-date" her. But as attraction and chemistry grow, their relationship becomes more than pretense. Things further evolve after Olive is harassed and belittled at a professional conference and Adam provides a supportive shoulder. But can their relationship hold up in the real world? With whip-smart and endearing characters, snappy prose, and a quirky take on a favorite trope, Hazelwood convincingly navigates the fraught shoals of academia. The delightful supporting characters, especially Adam's colleague Holden Rodriquez and Olive's friends Malcolm and Anh, add flavor—and readers will love seeing the villain of the story dispatched in appropriate fashion. This smart, sexy contemporary should delight a wide swath of romance lovers.

Customer Reviews

Amazing read.

I absolutely love this book! It’s funny, romantic, angsty, sexy, and offers the public a look into the absolutely draining (yet partially rewarding) life as a STEM grad student. Love the diversity and the message about the hardships marginalized grad students face in the cis-white-male dominated world of academia!

Such sass and much cuteness

Oh my god. I loved it. So much. Holy crap. The banter. The snark and the relationship dynamo between the main characters. Everything I could have hoped for. Get it. Get it. Get it. Devoured this book in a day.

STEM representation!!!

This book was every STEM girls dream 🤩 the man was smart and hot, supported the main lead, and the main lead was a strong independent woman but i lovedddd the progression and flow of this book. Also how it talked about such important aspects of STEM both good and bad. Definitely a good read!!! :)

Review: I loved this book! Some romance books are too cheesy for me but I thought this book was the perfect balance of cheesiness. I found Olive to be a relatable character; she was smart, funny, pretty and yet she still wasn’t always sure of herself. The trope of fake boyfriend turned to actual crush is a little overused but I liked how the author was aware of that and even poked fun of it. The first half of the book was a little slow, we all knew where the story was heading and I wish it got there a faster. Once the half way point was reached the story started to pick up and even got a little steamy. Personally I would have liked some more hot and heavy parts!

Not only was the romantic part of it great but I loved seeing the friendships in the book. Olive and Adam were able to build a strong friendship throughout the book even if their relationship was originally built on a lie. Olive has two best friends, Anh and Malcom. Olive has a different type of relationship with each of them but they are such pure friendships. It was nice to see a group of friends that was truly looking out for one another. The characters of Olive and Adam seemed a little flat and stereotypical at times but I think their outside friendships gave the reader a better view of who they are.

I was able to binge this book in two days (a little hard when you have a husband and a 2 year old)! This book is the perfect summer beach read, I highly recommend it to anyone who likes fun, lighthearted romances.
