Product Description 
The Instant New York Times Bestseller!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.\nAs 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.\nThat 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.\nSuddenly 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.

 About the Author 
Ali Hazelwood is the 
New York Times bestselling author of 
The Love Hypothesis, as well as the writer 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, eating cake pops, or watching sci-fi movies with her two feline overlords (and her slightly-less-feline husband).

Genre Fiction

BERKLEY

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. &nbsp; 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. &nbsp; 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?

Love on the Brain

Love, Theoretically

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. &nbsp; 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. &nbsp; 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. &nbsp; 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?
