This is the best book I have ever read. It's about a girl named Tally who lives 300 years in the future, with hoverboards, bunjee jackets and all the things we dream the future will be. But guess what? What do we all wnt to be? Beautiful. and in Tallys world when you turn 16 you get an operation that makes you pretty, then you move into the good part of town, where your only job is to have fun. There's a catch, you give up being smart basically. They take away your ability to question society. Three months before she turns 16 she sneaks off to see her best friend whose already pretty and if your ugly (in this world your pretty, ugly, or special, specials are the authority figures) you're not allowed to be in pretty town, she had to run away from the party her friend was at. While escaping she runs into a girl named Shay, who really doesn't want to be pretty, and some how they become friends. So when Shay runs away from the high-tech city to the smoke (a place ware rebbels go). then the authorities give Tally an awful choice, track Shay down and turn in everyone in smoke or never become pretty.
