The Love Hypothesis by Ali Hazel

One Fake Kiss. One Very Real Problem. One Hypothesis That Changes Everything.

Third-year PhD student Olive Smith doesn't believe in love — at least not for herself. But when she needs to convince her best friend that she's moved on from her ex, she impulsively kisses the first man she sees. That man turns out to be Adam Carlsen: brilliant, intimidating, and the most notoriously difficult professor in the biology department. The kind of man no one would ever believe she's dating.

Except Adam agrees to keep up the pretence. He has his own reasons for wanting people to think he's in a relationship. And as their fake dating arrangement continues, Olive starts to wonder whether her hypothesis about love — and about Adam — might be completely wrong.

The Love Hypothesis by Ali Hazel is the irresistible, witty, and deeply romantic novel that took BookTok by storm — a slow-burn, fake-dating romance set in the world of academic science, with a heroine you'll root for and a hero who will completely surprise you.
