This book concludes Vivian Apple's battle against the Church of America, which is less a church and more a mega corporation/cult. Vivian is smart and strong, but manages to make a few dumb mistakes along the way -- which makes her more realistic. Do any of us really know if we would make great choices at the end of the world? Viv's best friend, Harp, is great at both getting Viv into trouble and getting her out of it (the true mark of a great friend).

As the book reaches its end, the action amps up to edge-of-your-seat levels and leads to an incredibly satisfying conclusion.
