Unwind

It takes place in the United States in the near future. After the Second Civil War or the Heartland War, was fought over abortion, a compromise was reached, allowing parents to sign an order for their children between the ages of 13 and 18 to be unwound—taken to "harvest camps" and having their body parts harvested for later use. The reasoning was that since 99. 44% of the body had 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 13 for retroactive abortion have the option to "stork" their child by leaving it on another family's porch. If they don't get caught, the "storked" baby then becomes the other family's responsibility.
