Wait WHAT? What the hell just happened? What the hell was that? 
 I fell right into it, that's my problem with psychological/thriller: 
 1. I can't stop reading it until I know what happened for sure. 
 2. I never saw it coming. Well I had my suspicions but at the same time I was going with what (view spoiler)[Anna was saying and at the end I just fell for it (hide spoiler)] 
 And that last chapter was so frustrating, I wasn't that surprised but it was a good ending. Well I was a bit suprised. But.. we know what happened but at the same time we don't really know what happened. . 
 But that's what makes a good thriller in my opinion and this one was really good. I loved how she portrayed the characters: at the begining, you almost like them and at the end: you actually know their true nature and I ended up not liking them that much, I think at the end I hated all the main characters. But in those kind of books, that's really good. 
 So yeah, I liked it a lot and it made me want to read more psychological/thriller. I missed it.
