I just finished the audio of this book. Wow! If you like suspense, go out of your way to get your hands on this story. If you click on the cover you can read the first seven chapters free. If you're not hooked I'll be surprised. I have often wondered what it must be like to live in one of those communities of people who cut themselves off from the rest of the world. As a Texan I have vivid memories of the Waco incident and I've always wondered about the people who follow a leader like Koresh. This story provides a window. The plot moves along with building suspense and tension to a dramatic ending that has a little bit of a surprise along with the expected. The little surprise is, I'm sure, why there is going to be a sequel. I will HAVE to read it! This is not a book for young teens, but it is one that adults will enjoy as well as older teens.
