I was not prepared for this book to end yet, but Oz, was it wonderful. 
 This is such a good series. There's constant suspence, there's some horror and gore, romance, a lot of adventure, friendship, many different kinds of characters, all combined with a heroine who isn't your typical teenage girl at all, but who also isn't even close to perfect. A heroine who might also be the antagonist of the story, if she isn't careful. 
 The characters have varying degrees of depth, although since the series is written completely from Amy's point of view, they, too, are all viewed from her perspective. This obviously causes the impressions of the characters to be not entirely trustworthy, but it also enables the reader to really get into Amy's head - something I always like about books written in first-person POV. There are also several novellas in this series that are written from the perspectives of different characters; I might be reading those later on as well, just to get more insight into everyone else. 
 In any case, I love this series and am very glad I started reading it. I'll be twiddling my thumbs until the next book comes out and I can read on, because I can't wait to find out what happens next!
