Query: Excellent Book!

One of the best I've ever read.I recommend this book to parents. It is about teens, but not only for teens, as the message will speak to the parents as well.The demons letters were disturbing, but I wouldn't be a good mom if I wasn't at least a little bothered by what is going on in the world and how it effects our children.Where else will you read anything else like this, that boldly takes on spiritual issues and the insight of demons? It is definatly a good read.
