I won a contest and had several books to choose from and left this until last. The description didn't seem as interesting. I was wrong, this book is one of the best books I've read. It is well written, covers everything in the story and ties up the loose ends. It even gives you a view into the unwound clinics and how the unwinding takes place. The connections to all the characters all come together by the end of the book. I will certainly be reading more books written by Neal Shusterman.
