This book was a great second book in the zeros trilogy. There was a lot of intense and mysterious components to this story, which made it a very interesting read. I really liked the whole concept of the story, and the fact that there are a lot of parts where you can't even guess what's going to happen. Quite a bit of emotions are in this book to. An absolute have to read for people into suspense, adventure, friendship, and a little bit of mystery.
