I really liked this book, even though the two (three?) main characters are assholes. I really liked the way the author kept the tension up, practically through the whole story. After the first 40% book I looked up spoilers for the end, because I didn't really care about any of the characters, but once the 'real' Amy showed up things got really interesting. In fact, 'real' Amy was my favorite character in the whole book. Sure, she was crazy as shit, but she was also dedicated as fuck to her goal and was quippy while doing it. I think she had some of the best lines in the whole book. In the end this book was really gripping, interesting, and dark as shit which I really liked.
