Uglies is a 2005 science fiction novel by Scott Westerfeld. It is set in a future post scarcity dystopian world in which everyone is considered an "ugly," but then turned "Pretty" by extreme cosmetic surgery when they reach the age of 16. It tells the story of teenager Tally Youngblood who rebels against society's enforced conformity, after her friends Shay and David show her the downsides to becoming a "Pretty," even though it is obvious to most people.
