Samantha can't remember who she is. She doesn't even know her name until she's told it and even then it's foreign. The doctors call it dissociative amnesia and say it was caused by a traumatic event that had to have happened while she was missing. She doesn't remember being missing. She doesn't remember the people who show up at the hospital claiming to be her parents. She certainly doesn't remember Cassie, her supposed best friend who is still missing, or her brother or his best friend Carson. She's a stranger in her own life and the more she learns about who she was the happier she is that she doesn't remember. She might have ruled the high school, but she was horrible to everyone around her, friends and family alike. Even Sam's friendship with Cassie was more of the mean girl frenemy variety. Sam almost doesn't want to remember who she is and what she's done, but the only way to find Cassie is to remember what happened. 
 This book kept me on my toes the entire time. It's one of those books where you don't want to tell people anything because it will spoil the adventure. You never really know who you can trust as Sam begins to have hallucinations, that may or may not be memories. The disjointed flashes and mysterious notes are perfectly creepy. This story is a fantastic blend of thriller, mystery, humor, and romantic tension that left me yelling at the book's ending in shock.
