Loathe To Love You

Description from the Publisher:

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 on her way to a happily ever after was always going to be tough, scientists require proof. So, like any self-respecting woman, 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. This is why Olive is positively floored when he agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire and Adam surprises her again with his unyielding support (and his unyielding abs), their little experiment feels dangerously close to combustion.

Olive soon discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuro-engineering project - a literal dream come true - Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.

Sure, Levi is attractive in a tall, dark, and piercing-eyes kind of way. But Levi made his feelings toward Bee very clear in grad school - archenemies work best employed in their own galaxies far, far away.

But when her equipment starts to go missing and the staff ignore her, Bee could swear she sees Levi softening into an ally, backing her plays, seconding her ideas... devouring her with those eyes. The possibilities have all her neurons firing.

But when it comes time to actually make a move and put her heart on the line, there's only one question that matters: What will Bee Königswasser do?

Mara, Sadie, and Hannah are friends first, scientists always. Though their fields of study might take them to different corners of the world, they can all agree on this universal truth: when it comes to love and science, opposites attract, and rivals make you burn....

Under One Roof

An environmental engineer discovers that scientists should never cohabitate when she finds herself stuck with the roommate from hell - a detestable big-oil lawyer who won't leave the thermostat alone.

Stuck with You

A civil engineer and her nemesis take their rivalry - and love - to the next level when they get stuck in a New York elevator.

A NASA aerospace engineer's frozen heart melts as she lies injured and stranded at a remote Arctic research station and the only person willing to undertake the dangerous rescue mission is her longtime rival.

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

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. 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 (Review, Recap & Full Summary)

By ali hazelwood.

Book review, full book summary and synopsis for The Love Hypothesis by Ali Hazelwood, a delightful rom-com about a fake relationship between a biology Ph.D. student and a professor.

In The Love Hypothesis , Olive is a third-year biology Ph.D. candidate who shares a kiss with a handsome stranger in order make her friend think that she's in a relationship. She's horrified when she realizes the "stranger" is Dr. Adam Carlson, a prominent professor in her department who is known for being a hypercritical and moody tyrant.

She and Adam each have reasons for needing to be in a relationship, and they agree to pretend to date for the sake of appearances. Of course, as she gets to know Adam, it's only a matter of time before she starts feeling something for him, and it becomes clear that her little experiment in fake-dating just might combust...

(The Full Plot Summary is also available, below)

Full Plot Summary

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.

Book Review

The Love Hypothesis by Ali Hazelwood came out a few months ago, and I didn’t really pay much attention to it. However, people seem to really be enjoying this book, and after reading The School for Good Mothers , I was really in mood for something light and fun.

In the Love Hypothesis, Olive is a third-year biology Ph.D. student at Stanford who ends up fake-dating a young and handsome tenured professor in her department. All the usual rom-com shenanigans ensue.

The Love Hypothesis is an unapologetically cheesy rom-com novel — with an upbeat attitude, meet cutes, fake-dating tropes, etc. — but it’s also a genuinely fun and often funny book. It hits a lot of familiar notes if you’re familiar with this genre, but somehow Ali Hazelwood has arranged them in a way that ends up being delightful and entertaining.

The book is super melodramatic at parts, uses so many tropes I couldn’t even list them all here if I was inclined to do so and is predictable in the way that rom-coms are always kind of predictable. That all said, I still had a fantastic time reading it and it flew by.

This is a short review because honestly it’s not that complicated to explain that this book is super cheesy and super fun.

Read it or Skip it?

If you like “chick lit” and rom-coms, you should definitely look into this book. I tend to be a little hypercritical of books in this genre, but I really enjoyed The Love Hypothesis . I found myself smiling and chuckling quite a bit as I read it.

This book is a straight-up cheesy rom-com — it is funny, melodramatic and fun as hell. I thought it was great.

The Love Hypothesis Audiobook Review

Narrated by : Callie Dalton Length : 11 hours 8 minutes

I listened to about half of this on audiobook. I think the audiobook is solid. The narrator is easy to listen to and does a good job with it.

With an exclusive new bonus chapter...from Adam's POV

Based on the available information and the data hitherto collected, my hypothesis is that the further I stay away from love, the better off I will be.
