This is the second book in the Unwind Trilogy by Neal Shusterman. It has been at least 4 years since I read the first book the in series, but I was able to pick up with Conner, Lev & Risa fairly quickly. I love these characters. Dystopian fiction at it's best! Society has decided that the answer to the war on abortion is to allow parents to have their children "unwound" between the ages of 13 and 17. Advocates claim the child is not killed, but living in a "divided state" -- their bodies are essentially separated into various parts and used for transplants to heal others. Those slated to be unwound don't feel the same way. This book picks up after the explosion and riot at one of the "Harvest Camps". There are parts pirates, and we are introduced to Cam, a teen who never existed.
