YES. JUST YES. 
 This book is one of the best sequels I've ever read. I was a bit scared that this book would be just a copy of the first book, but it was different, it was so much more, it was just as dark, it was just as creepy, it was just as terrifying and it was just as good. 
 I still really like Deanna. She is one of the most interesting character I have ever read about. She is complex, she is intense and scary but she is so likeable. 
 This book doesn't focus as much on the whole cam thing. We get to see Deanna trying to get more freedom, to get out more, (without killing anyone). 
 I adore her relationship with cute Jeremy, again complex but I love them so much. 
 Marcus, the bad guy, psychopath of this book was just as scary as Ralph. He freaked me out SO SO MUCH. And we got to read a lot from his pov, so we had to read his twisted thoughts a lot. He honestly made me want to locked myself up and never get out of my house ever again.. 
 And yes this book was so so good. It kept me on the edge of my seat. It was stressful, terrifying and so addictive. 
 These books are so addictive and I can't wait to read the next one.
