Charlie (Charlotte) is in the business of breaking men's hearts to make them become better, wholesome, husband material men. She begins a secret club of girls who disguise themselves to take down some of the biggest jerks out there. It's only after being assigned her toughest case yet, does she take on the challenge herself. Disguising herself to be ugly and un-presentable, she challenges her college's biggest player to have a relationship with her. Can she follow her own rules and not fall in love?

Stella’s not like most girls. She doesn’t spend her nights talking about cute boys or who she’s going out with next week. Cause really, what’s the point in that? When a new kid, Jace Matthews transfers to her school, she’s probably the only girl not under his charm, making her Jace’s number one target. It seems like he just won’t leave Stella alone, and she’s left with her last resort: fighting fire with fire. Someone needs to teach pretty boy a lesson, and Stella’s the perfect girl to do it.
