This is the sequel to UnWind. Both books are excellent. I read UnWind in a day. This is so good, plus I'm working and it's taking longer to read. One of the reasons that it's taking longer is that I have to think about what I just read. Shusterman is brilliant! You will not be disappointed. The characters are strong and solid. The believability, spot on.
Imagine you are 15 years old. Now imagine the adults wanting to harvest you for parts. It's a crazy world. If you are not a reader, you will be after reading Neil Shusterman. He gets better every year. A writer worth watching.
