This book was awesome, truly one I didn't want to put down once I started reading. The nature of the story would keep me from picking up the book sometimes, b/c it gets pretty dark, and once you start reading it's really hard to stop. The audio version was also fantastic. 
 You get very invested in the characters, and I love the dual narration perspective the author used. And the ending is kind of unsettling, but I loved it.
