Pretties, sequel to Uglies, is a book about Tally Youngblood. Tally lives in a futuristic city where when you turn 16, you become pretty. Where your bones get replaced by titanium and you become beautiful. It doesn’t seem like it could be bad, but, it is in some ways. In Pretties, Tally finds herself without lesions, a “disease” that gets put into Pretties to change the way they think. That way, they are powerless, all they like to do is drink and have fun. But Tally is getting hunted down by specials, a secret government group meant to keep the city in order. They are myths and rumors to most, but to Tally, the word gives her nightmares.
