My killer is out there.

And my sister might be next.

Two months before I died, my best friend's brother disappeared. I have no idea where Thayer went 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 unraveling the many mysteries I left behind - my cryptic journal, my tangled love life, the dangerous Lying Game pranks I played. She's uncovered my 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.

From Sara Shepard, the #1 New York Times bestselling author of the Pretty Little Liars books, comes a riveting series about secrets, lies, and killer consequences.
