Seventeen-year-old Ellie Garcia thought she had reasonable expectations for senior year: to see her friends after a long summer, not be drenched in sweat before 7 AM, and run her first meeting as team leader of her volunteer group. She didn't expect everyone to be passing around a list of boys at school to avoid because they assaulted fellow classmates. Or for the boys on the list to start dying one by one.

Ellie has always wanted to be a detective, so when she's a person of interest in one of the boy's deaths, she wants to investigate and clear her name. When her best friends refuse to help, she teams up with the quirky coroner intern who owes her a favor. The more she learns, the more she realizes that everyone has a secret-even those closest to you.
