The Love Hypothesis

One Fake Kiss. One Very Real Problem.

Third-year PhD student Olive Smith doesn't believe in lasting romantic relationships — but she does believe in science, and right now the data strongly suggests she needs a fake boyfriend. Fast. When she kisses the first man she sees, she doesn't expect it to be the notoriously intimidating Professor Adam Carlsen. And she certainly doesn't expect him to agree to keep up the ruse. What follows is a slow-burn fake-dating romance that is equal parts hilarious, swoony, and genuinely moving — set against the pressures and politics of academic life in a STEM PhD programme.

The Love Hypothesis by Ali Hazelwood is the TikTok sensation that took the world by storm and introduced readers everywhere to the joy of STEM romance. Warm, witty, and deeply satisfying, it is the kind of book you will stay up far too late reading — and immediately want to recommend to everyone you know.
