Samantha has no memory of her life before she was found wandering on a street after she had been missing for several days. She learns that before she disappeared with her best friend Cassie she was the most popular mean girl in school with the perfect boyfriend. But she doesn't remember that life and now she can't imagine living it. In fact, the more she learns about who she was before the more disgusted she is with herself and the more determined she is to not go back to being that person. But Cassie is still missing and Sam is struggling to remember her past to help find her, even if it sounds like they were more like rivals than friends. Trouble is, Sam is pretty sure someone was trying to kill her the night she disappeared and she can't be sure who to trust when so many people had a reason to want her dead.
I really, really enjoyed this book. Sure, there's nothing new or deep here, just a fun mystery with lots of red herrings and a surprise twist at the end.
