I don't do a lot of book reading, but Jirue introduced me to this book and I loved it.
The guy's other books are pretty good too.
Edit:
Unwind is a 2007 science fiction novel by young adult literature author Neal Shusterman. It takes place in the United States, somewhere in the near future. After a civil war—known as the Second Civil War or the Heartland War—is fought over abortion, a compromise was reached, allowing parents to sign an order for their children between the ages of 13 and 18 years old to be unwound—taken to "harvest camps" and having their body parts harvested for later use. The reasoning was that, since 100% (actually 99.44% taking into account the appendix and "useless" organs) was required to be used, unwinds did not technically "die", because their individual body parts lived on. In addition to unwinding, parents who are unable to raise their children to age thirteen for retroactive abortion have the option to "stork" their child by leaving it on another familys doorstep. If they don't get caught, the "storked" baby then becomes the other family's responsibility.
