My perfect life was a lie.

Now I'd do anything to uncover the truth. Not long ago, I had everything a girl could wish for: amazing friends, an adorable boyfriend, a loving family. But none of them know that I'm gone - that I'm dead and that my long-lost twin sister, Emma, has taken my place to solve my murder.

But the deeper she digs, the more suspects she uncovers. It turns out my friends and I played a lot of games - games that ruined people's lives. Anyone could want revenge . . . anyone could want me - and now Emma - dead.
