A forbidden, secret affair proves that all's fair in love and science - from Sunday Times and 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.

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…)

This novel is suitable for both young adult and adult audiences.

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 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. Which 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.

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 New York Times bestselling author of 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 an historic peacekeeping alliance between the Vampyres and their mortal enemies, the Weres, and 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.

Rival physicists collide in a vortex of academic feuds and fake dating shenanigans in this delightfully STEMinist romcom.

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 favourite 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?

Three irresistible short stories by the global phenomenon Ali Hazelwood, now available together in paperback for the first time, with an exclusive bonus chapter.

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.

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.

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?
