Tally Youngblood is quickly approaching her 16th birthday and the mandatory pretty-making surgery that accompanies it. But Tally isn't sure if she wants to be a placidly happy Pretty. When a top secret organization threatens her with remaining Ugly forever, she reluctantly spies on the rebels who have refused the surgery. They think it changes more than just looks and are working on a cure. But they need someone to become Pretty to test it out. "Teens will sink their teeth into the provocative questions ... [in this] high concept YA fiction that has wide appeal."-Booklist, starred review
