Lizzie's reputation is destroyed when she's caught in bed with her best friend's boyfriend on prom night. With the whole school turned against her, and Angie not speaking to her, she takes her own life. But someone isn't letting her go quietly. As graffiti and photocopies of Lizzie's diary plaster the school, Angie begins a relentless investigation into who, exactly, made Lizzie feel she didn't deserve to keep living. And while she claims she simply wants to punish Lizzie's tormentors, Angie's own anguish over abandoning her best friend will drive her deep into the dark, twisted side of Verity High--and she might not be able to pull herself back out.
