The Instant New York Times Best Seller and TikTok Sensation! 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. As a third-year PhD 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.
A glimpse inside

Olive, a pragmatic PhD candidate, approaches life—and love—with the mindset of a scientist: logical, skeptical, and data-driven. The novel explores how her attempts to rationalize feelings clash with the unpredictable, chaotic nature of real attraction and vulnerability. This tension drives much of the story’s humor and heart, as Olive learns that some of life’s most meaningful experiences can’t be measured or controlled.
The central trope—fake dating—serves as more than a plot device. It becomes a crucible for Olive and Adam to confront their insecurities, boundaries, and desires. Pretending to be together forces both characters to drop their guard, revealing truths about themselves and each other. The book examines how pretending can paradoxically lead to genuine connection and self-discovery.
