Whoa. This book was seriously disturbing. Also uplifting in a way-- the relationship of the captives and their (re)discovery of life outside of the box, that kind of thing-- but really the knowledge that the ending would be a relatively happy one was the only thing that kept me reading. MAJOR TRIGGER WARNING: if scenes of child & sexual abuse upset you, this is definitely not a book you'll want to read. That's not to say that the book isn't well-written, because it is very well-written, but I can't really recommend this book willy-nilly to everyone because of the content.
