Tally can't wait to turn sixteen. Only then will she be able to have an operation to turn her from a repellent ugly into a stunningly attractive pretty and live in New Pretty Town, the high-tech paradise, where her only job will be to have fun.
But when Tally finally becomes pretty, everything isn't as perfect as it seems. Underneath all the beauty and luxury is a nagging sense that something is wrong. Very wrong.
Searching for the truth, Tally discovers a whole new side of the pretty world - and it isn't very pretty. Now Tally has a choice to make: fight to forget what she knows, or fight for her life.
