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, 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.
