This book was interesting but the ending felt rushed, even abrupt in how quickly it came. Things did not wrap up completely, which is fine with a book like this, but the speed with which some of the story lines ended was dizzying. There is also a moment when A wakes up in the body of a heavy boy that made me annoyed at both A and Rhiannon. I felt as if A wasn't as good at looking at the people he inhabited complexly as I would have liked. Still the story was interesting and a quick, though provoking read.
