17 year old Jessamine Taylor has just recently moved to California after her parents both get job promotions. She's very excited to be moving to a new state. The only thing that catches her off guard is one of Hamminton High School's bad boys, Harry Styles. Something is different about this boy, and she wants to find out.

Harry is the most popular guy in school, along with Aiden, his twin brother. They're gorgeous, they're strong, and they know how to win girls' hearts. But that doesn't change the fact that they're total jerks. Denise is Aiden and Harry's favorite target. After Denise gets into a near-death car accident, her memory is gone. For a dare, Harry pretends Denise and him are best friends, while Aiden, on the other hand, doesn't approve. Does anything change between them? Or is Harry still the jerk that he always was?
