Two months before I died, my best friend's brother went missing. I have no idea where Thayer is or why he left, but I know it's my fault. I did a lot of horrible things while I was alive, things that made people hate me—maybe even enough to kill me.

Desperate to solve my murder, my long-lost twin, Emma, is pretending to be me and looking into the many mysteries I left behind. She's uncovered my closest friends' darkest secrets, but she's never had the chance to dig into Thayer's past—until now.

Thayer's back, and Emma has to move fast to figure out if he's after revenge . . . or if he's already gotten it.
