I had a hard time getting into this one, but once I did it was great! The end was much better than the beginning. Green took a bit to build up into the action, but by the end of the book I was sucked in. Nice beginning to a series.
Great story! I'm hooked. I'm eagerly awaiting the next book in the series. The concept of a secret Underground filled with undead with a sinister agenda is terrific! I also love the members of the team searching for the main character's father. Can't wait!
