Unwind by Neal Shusterman

The Heartland Wars are over. A compromise was reached between the pro-life and pro-choice crowds. Abortion is illegal, but there are still options. Parents can choose to have their 13-18 year old unwound, a process in which the child does not die, but every part is harvested for transplant. Naturally, some people have a problem with this. Namely, the kids who are going to be unwound. Kids like Connor and Risa. Connor is impulsive, always getting in fights and trouble at school. He gets suspicious when he finds three plane tickets to the Caribbean when there are four people in his family. Then he finds the unwind order. He runs away, gets caught, and causes a major traffic accident in the process of escaping. Risa grew up in a state home. Budget cuts mean that some kids have to be unwound. When she doesn't play her piano piece perfectly (she's been studying to be a classical pianist) she is told she'll be unwound. When her bus is involved in a traffic accident, she makes a break for it. Lev is a tithe. His sole purpose is to be unwound, and he's been preparing for it his whole life. "Rescued" by Connor, who then teams up with Risa, all Lev wants to do is escape and get on with his unwinding.
Part of the current crop of teen dystopias, Shusterman's tale has some truly horrifying and heartbreaking moments. The teens in this story are not placed in danger by a merciless government, but by their own parents. Told in alternating viewpoints between Connor, Risa, and Lev, the book has sympathetic characters, consistently good writing, and a quick pace. The ending is hopeful, though not happy. I would expect it to appeal to fans of other teen dystopias, as well as those looking for fiction that explores parental abandonment, rights, and responsibilities; law and morality; what it means to be alive; and self determination.
