Ali Hazelwood Books with Descriptions
If you’re looking to dive into Ali Hazelwood’s books, you’ll find all of her books below with the publisher’s descriptions. Each book is in order of the publication date.
The Love Hypothesis by Ali Hazelwood
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.
Under One Roof by Ali Hazelwood
A scientist should never cohabitate with her annoyingly hot nemesis—it leads to combustion.
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 …
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.
The problem is, living with someone means getting to know them. And the more Mara finds out about Liam, the harder it is to loathe him … and the easier it is to love him.
Stuck with You by Ali Hazelwood
Nothing like a little rivalry between scientists to take love to the next level.
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 …
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.
Not even the most sophisticated of Sadie’s superstitious rituals could have predicted such a disastrous reunion. But while she refuses to acknowledge the siren call of Erik’s steely forearms or the way his voice softens when he offers her his sweater, Sadie can’t help but wonder if there might be more layers to her cold-hearted nemesis than meet the eye. Maybe, possibly, even burned bridges can still be crossed …
Below Zero by Ali Hazelwood
It will take the frosty terrain of the Arctic to show these rival scientists that their chemistry burns hot.
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 …
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?
Love on the Brain by Ali Hazelwood
From the New York Times bestselling author of The Love Hypothesis comes a new STEMinist rom-com in which a scientist is forced to work on a project with her nemesis—with explosive results.
Like an avenging, purple-haired Jedi bringing balance to the mansplained universe, Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project—a literal dream come true after years scraping by on the crumbs of academia—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. 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.
Now, her equipment is missing, the staff is ignoring her, and Bee finds her floundering career in somewhat of a pickle. Perhaps it’s her occipital cortex playing tricks on her, but Bee could swear she can see Levi softening into an ally, backing her plays, seconding her ideas … devouring her with those eyes. And 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?
Loathe to Love You by Ali Hazelwood
From the New York Times bestselling author of The Love Hypothesis comes a collection of steamy, STEMinist novellas featuring a trio of engineers and their loves in loathing—with a special bonus chapter!
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.
Below Zero
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.
Love, Theoretically by Ali Hazelwood
Rival physicists collide in a vortex of academic feuds and fake dating shenanigans in this delightfully STEMinist romcom from the New York Times bestselling author of The Love Hypothesis and Love on the Brain.
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.
Elsie is prepared for an all-out war of scholarly sabotage but … those long, penetrating looks? Not having to be anything other than her true self when she’s with him? Will falling into an experimentalist’s orbit finally tempt her to put her most guarded theories on love into practice?
Check & Mate by Ali Hazelwood
In this clever and swoonworthy YA debut from the New York Times bestselling author of The Love Hypothesis, life’s moving pieces bring rival chess players together in a match for the heart.
Mallory Greenleaf is done with chess. Every move counts nowadays; after the sport led to the destruction of her family four years earlier, Mallory’s focus is on her mom, her sisters, and the dead-end job that keeps the lights on. That is, until she begrudgingly agrees to play in one last charity tournament and inadvertently wipes the board with notorious “Kingkiller” Nolan Sawyer: current world champion and reigning Bad Boy of chess.
Nolan’s loss to an unknown rook-ie shocks everyone. What’s even more confusing? His desire to cross pawns again. What kind of gambit is Nolan playing? The smart move would be to walk away. Resign. Game over. But Mallory’s victory opens the door to sorely needed cash-prizes and despite everything, she can’t help feeling drawn to the enigmatic strategist …
As she rockets up the ranks, Mallory struggles to keep her family safely separated from the game that wrecked it in the first place. And as her love for the sport she so desperately wanted to hate begins to rekindle, Mallory quickly realizes that the games aren’t only on the board, the spotlight is brighter than she imagined, and the competition can be fierce (-ly attractive. And intelligent … and infuriating …)
Bride by Ali Hazelwood
A dangerous alliance between a Vampyre bride and an Alpha Werewolf becomes a love deep enough to sink your teeth into in this new paranormal romance from the #1 New York Times bestselling author of Love, Theoretically and The Love Hypothesis.
Misery Lark, the only daughter of the most powerful Vampyre councilman of the Southwest, is an outcast—again. Her days of living in anonymity among the Humans are over: she has been called upon to uphold a historic peacekeeping alliance between the Vampyres and their mortal enemies, the Weres, and she sees little choice but to surrender herself in the exchange—again …
Weres are ruthless and unpredictable, and their Alpha, Lowe Moreland, is no exception. He rules his pack with absolute authority, but not without justice. And, unlike the Vampyre Council, not without feeling. It’s clear from the way he tracks Misery’s every movement that he doesn’t trust her. If only he knew how right he was …
Because Misery has her own reasons to agree to this marriage of convenience, reasons that have nothing to do with politics or alliances, and everything to do with the only thing she’s ever cared about. And she is willing to do whatever it takes to get back what’s hers, even if it means a life alone in Were territory … alone with the wolf.
Not in Love by Ali Hazelwood
A forbidden, secret affair proves that all’s fair in love and science—from New York Times bestselling author Ali Hazelwood.
Rue Siebert might not have it all, but she has enough: a few friends she can always count on, the financial stability she yearned for as a kid, and a successful career as a biotech engineer at Kline, one of the most promising start-ups in the field of food science. Her world is stable, pleasant, and hard-fought. Until a hostile takeover and its offensively attractive front man threatens to bring it all crumbling down.
Eli Killgore and his business partners want Kline, period. Eli has his own reasons for pushing this deal through—and he’s a man who gets what he wants. With one burning exception: Rue. The woman he can’t stop thinking about. The woman who’s off-limits to him.
Torn between loyalty and an undeniable attraction, Rue and Eli throw caution out the lab and the boardroom windows. Their affair is secret, no-strings-attached, and has a built-in deadline: the day one of their companies will prevail. But the heart is risky business—one that plays for keeps.
Two Can Play by Ali Hazelwood
An enemies-to-lovers spicy romance set in the world of video gaming from the bestselling author of The Love Hypothesis—available only in audio!
Viola Bowen has the chance of a lifetime: to design a video game based on her all-time favorite book series. The only problem? Her co-lead is Jesse F-ing Andrews, a.k.a. her arch-nemesis. Jesse has made it abundantly clear over the years that he wants nothing to do with her–and Viola has no idea why.
When their bosses insist a wintery retreat is the perfect team-building exercise, Viola can’t think of anything worse. Being freezing cold in a remote mountain lodge knowing Jesse is right next door? No, thank you.
But as the snow piles on, Viola discovers there’s more to Jesse than she knew, and heat builds in more ways than one.
Cruel Winter with You by Ali Hazelwood
For two former childhood friends, a blustery winter storm stirs some frosty—and scorching—memories in a delightful short story by #1 New York Times bestselling author Ali Hazelwood.
All newly minted pediatrician Jamie Malek wants is to borrow a roasting pan for Christmas dinner. Unfortunately, that requires her to interact with Marc—her best friend’s troublemaking brother, who’s now a tech billionaire. He’s the one who got away. She’s the one who broke his heart. Outside, a howling blizzard. Inside, a crackling fire. Suddenly, being snowbound with the man she never expected to see again might not be such a bad way to spend a winter’s night.
Ali Hazelwood’s Cruel Winter with You is part of Under the Mistletoe, a stirring collection of December romances that thrill and tingle all the way. They can be read or listened to in one swoony sitting.
Deep End by Ali Hazelwood
A competitive diver and an ace swimmer jump into forbidden waters in this steamy college romance from the New York Times bestselling author of The Love Hypothesis.
Scarlett Vandermeer is swimming upstream. A junior at Stanford and a student-athlete who specializes in platform diving, Scarlett prefers to keep her head down, concentrating on getting into med school and on recovering from the injury that almost ended her career. She has no time for relationships—at least, that’s what she tells herself.
Swim captain, world champion, all-around aquatics golden boy, Lukas Blomqvist thrives on discipline. It’s how he wins gold medals and breaks records: complete focus, with every stroke. On the surface, Lukas and Scarlett have nothing in common. Until a well-guarded secret slips out, and everything changes.
So they start an arrangement. And as the pressure leading to the Olympics heats up, so does their relationship. It was supposed to be just a temporary, mutually satisfying fling. But when staying away from Lukas becomes impossible, Scarlett realizes that her heart might be treading into dangerous water …
Problematic Summer Romance by Ali Hazelwood
What is wrong meets what feels right in this romance set in Italy by the New York Times bestselling author of Deep End.
Maya Killgore is twenty-three and still in the process of figuring out her life.
Conor Harkness is thirty-eight, and Maya cannot stop thinking about him.
It’s such a cliché, it almost makes her heart implode: older man and younger woman; successful biotech guy and struggling grad student; brother’s best friend and the girl he never even knew existed. As Conor loves to remind her, the power dynamic is too imbalanced. Any relationship between them would be problematic in too many ways to count, and Maya should just get over him. After all, he has made it clear that he wants her gone from his life.
But not everything is as it seems—and clichés sometimes become plot twists.
When Maya’s brother decides to get married in Taormina, she and Conor end up stuck together in a romantic Sicilian villa for over a week. There, on the beautiful Ionian coast, between ancient ruins, delicious foods, and natural caves, Maya realizes that Conor might be hiding something from her. And as the destination wedding begins to erupt out of control, she decides that a summer fling might be just what she needs—even if it’s a problematic one.
Hot for Slayer by Ali Hazelwood
When a vampire slayer loses all his memories, the only person who can help him is the vampire he’s tried to kill for centuries in this unforgettable short story by #1 New York Times bestselling author Ali Hazelwood.
When Aethelthryth—”Ethel” to her modern-day Manhattan neighbors—finds her sworn nemesis Lazlo Enyedi with no memory of who or what they are, an ancient hunt becomes an unexpected chance at forbidden passion. He’s crashing on her couch, solving her sudoku puzzles, and looking at her like she’s his eternal flame (minus the whole bursting-into-ashes part). As his memories slowly return, Ethel realizes she might be in danger of losing more than just her head …
Ali Hazelwood’s Hot for Slayer is part of Scared Sexy, a deliciously dark collection of Halloween romance where things that go bump in the night might just steal your heart. These seductive stand-alone stories blend chills and heat in the perfect Halloween treat—designed to be devoured in one sitting.
Mate by Ali Hazelwood
A Human hybrid and an Alpha Were claw against the bonds of fate in the highly anticipated companion novel to the New York Times bestselling Bride.
Serena Paris is orphaned, pack-less, and one of a kind. Coming forward as the first Human-Were hybrid was supposed to heal a centuries-long rift between species. Instead, it made her a target, prey to the ruthless political machinations between Weres, Vampyres, and Humans. With her enemies closing in on her, she has only one option left—if he’ll have her.
As Alpha of the Northwest pack, Koen Alexander commands obedience. His authority is so absolute, only a fool would threaten his mate. It doesn’t matter if Serena doesn’t reciprocate his feelings, nothing will stop him from keeping her safe.
But power-hungry Vampyres and Weres are not the only threats chasing Serena. Sooner or later, her past is bound to catch up with her—and Koen might be the only thing standing between her and total annihilation …
Is There a Reading Order for Ali Hazelwood’s Books?
There’s no set reading order for Ali Hazelwood’s books since they’re all standalone romances. This means you don’t have to worry about reading them in a specific sequence — you can pick up whichever title catches your interest first.
That being said, some readers like to follow her books in the order they were published. This allows you to see how her writing has grown over time and enjoy the variety of her stories in the order they were released. I personally started with her debut, The Love Hypothesis, and would recommend it as a great place to start.
It’s also worth noting that Bride and its upcoming sequel, Mate, are connected. While they’re technically standalones, you may enjoy them more if you read them in order.
The short answer: you can read Ali Hazelwood’s books in any order you like—it’s all up to personal preference!

If you’re new to Ali Hazelwood, the best place to start is with her debut novel, The Love Hypothesis. Not only is it her most popular book, but it’s also the one that first captured readers’ hearts with its fake-dating trope, STEM setting, and swoony romance.
From there, you can branch out depending on what you’re in the mood for:
- If you want more STEM rom-coms, check out Love on the Brain or Love, Theoretically.
- If you prefer something shorter, her STEMinist novellas, collected in Loathe to Love You, are a fun option.
- If you’re in the mood for young adult romance, try Check & Mate.
- Or, if you love a twist of the paranormal, Bride is a great place to dive in—especially with its sequel, Mate, releasing soon.

If you’re looking for something on the lower end of the spice scale, her STEMinist novellas, collected in Loathe to Love You, or her young adult novel Check & Mate, are a great place to start. They’re still romantic and flirty but lighter in heat compared to her other adult novels.
