I quite enjoyed this book and particularly Picoult's easy, flowing style of writing. The short chapters allowed it to be a page turner and the story was well thought out, clever and kept you interested. However, the ending let me down. It leaves a lot of unanswered questions and loose ends I would have liked to be tied up before it ended. But because I'm left with these questions, I don't think I'll forget these characters in a hurry.
