In America after the Second Civil War, the Pro-Choice and Pro-Life armies came to an agreement: the Bill of Life states that human life may not be touched from the moment of conception until a child reaches the age of 13. Between the ages of 13 and 18, however, a parent may choose to retroactively get rid of a child through a process called "unwinding." Unwinding ensures that the child's life doesn't really end because all the organs are transplanted to various recipients. Now a common and accepted practice in society, unwinding is an easy way to deal with troublesome or unwanted teens. With breathtaking suspense, this book follows three teens who all become runaway Unwinds: Connor, a rebel whose parents have ordered his unwinding; Risa, a ward of the state who is to be unwound due to cost-cutting; and Lev, his parents' 10th child, whose unwinding has been planned since birth as a religious tithing. As the characters' paths intersect and their lives hang in the balance, author Neal Shusterman examines serious moral issues in a way that will keep readers turning the pages.
