Holy crap things got really sad in this one, when you find out what a lot of these characters went through in their past. This book really focused on depression and overcoming it, and I couldn't help but feel a lot happier after reading it. There are so many great messages in this series that make me look forward to the other books, just to learn something new. As far as the story goes, this series looks like it's going to have a crazy endgame. Whatever kind of outcome Nick is going to have, whether he destroys the world or not, I look forward to seeing it.
