I bought this series for my teenage daughter a couple years ago, but she hasn't read them yet. So I will instead! This is the first book in the series, it counts down to 1. This is definitely written for a younger audience, probably middle school aged. I finished it in just about 2 hours. The story was pretty good, but I didn't like the ending. Phelan left a major cliffhanger that I suspect will continue through the end of the series.
