Rating: 3.5/5 
 ***Minor spoilers*** 
 Samantha doesn't know what happened to her. Her earliest memory is when she was just walking barefoot along a road and a cop car pulled up and brought her to the hospital, and the parents she can't remember. She doesn't know where she was or what happened, and the hospital said that she wasn't assaulted. Better yet, she disappeared at the same time as her best friend Cassie, who hasn't been found yet. It's possible that Sam was the last person to see Cassie alive, but without her memories, she'll never get closure. 
 I've never really liked books where the main character has amnesia. I'm a person who likes knowing a lot about the characters and what's going on. I find it irritating when it's hard to figure out what's going on, which is why I usually hesitate to pick up amnesia books. Usually I have a hard time identifying with the main characters, and in this book she didn't even remember her friends, brother, or parents, but somehow I still liked Sam as a character. I know a lot of people criticized her in their reviews because she seemed very dense, but I liked her. She was obviously in a very confused emotional state so I didn't blame her for being pretty out of it and not very perceptive. 
 I really enjoyed the mystery aspect of this book. I love murder mystery and crime novels, even though I don't read too many of them because most of them are adult books and I'm not a big fan of those. This book kept me guessing right until the end. I had over 4 different theories that kept being juggled around because of different things happening in the book, but I didn't think it was very obvious. The killer was someone I suspected, but wasn't at the top of my list. While that part of the ending didn't entirely surprise me, the rest of the ending did. All of the mystery throughout the book led to one big blowup, and I enjoyed how the book ended. I felt like the epilogue just put everything together for me. 
 Overall, I enjoyed this book more than I thought I would while reading the first quarter or so. This is my second book by Jennifer L Armentrout, the other being Obsidian, and I'm not sure which I liked better. I think I liked them equally. I'd recommend this book if you're into murder mysteries and you enjoy the suspense leading up to finding out what really happened.
