Plot Summary

The Love Hypothesis is set in modern-day America and follows Olive Smith, a 26-year-old graduate student of biology at Stanford University. Olive’s research focuses on pancreatic cancer, but each chapter begins with a hypothesis about Olive’s love life or choices as is relevant to the chapter’s contents.

Two years before the main events of the story, Olive’s expired contacts act up right before her interview for Ph.D. candidacy at Stanford. While she waits in the bathroom for her eyes to stop watering, she meets Adam Carlsen, one of the foremost biology researchers in the world—though she doesn’t learn it was him until the end of the book.
