Love, Theoretically by Ali Hazelwood is a smart, swoony romantic comedy about a physicist who's an expert at theoretical scenarios—but completely unprepared for the chaos of real-life love.

Elsie Hannaway is a theoretical physicist who's mastered the art of being whoever people need her to be. As an adjunct professor bouncing between universities, she's learned to adapt, blend in, and never make waves. But when she's hired to consult on a major project, she comes face-to-face with the one person who sees through her act: Jack Smith, the older brother of her ex-boyfriend and the man she's been trying to forget.

Jack is brilliant, infuriating, and completely off-limits. But as they're forced to work together, the chemistry between them becomes impossible to ignore. Now Elsie must decide whether to stick to her carefully calculated life plan or take a risk on something real.
