Yes, this book was twisted and creepy and dark. I changed my mind about what was going on after just about every chapter. It's strange imagining people who think like these characters do. It's frightening to think there might be people out there who actually do. I was drawn into this book by its creepy premise and kept coming back for the characters I was both believing and hating. It was a crazy ride. We get to follow Nick's POV from the day of Amy's disappearance forward and Amy's POV from the moment the two met until her disappearance. It was definitely an interesting take on a double POV and was done very well. The first half had great buildup and lots of creepy moments. But I have to admit after the first half there were more "oh, okay" moments than there were truly shocking moments. In the end, I was somewhat disappointed. I had expected an intense, twisted, psychological thriller but in the end it seemed more like just a psychological study of crazy people. And that's fine. Because it was twisted. But it just didn't quite meet up with my expectations. I should maybe mention this is my first Gillian Flynn novel. So really, I'm just disappointed in the ending. But the more I think about it, the more it seems like the only possible ending. So I'm torn. And it will get three stars from me for right now. Maybe it'll change later. I've heard from some people that they like her other books better, so I may check them out. I'm still glad I read this. I know I'll be thinking about it for a long time. It'll take some time to sort through all of my emotions. Also, this would make a great book club book.
