Uglies by Scott Westerfeld
In a world where everyone is cosmetically enhanced to be absolutely beautiful at 16, how can anything be wrong??? Tally can’t wait to join her best friend, Peris, who became a Pretty a few months ago. She misses him a lot, but finds a new buddy, Shay, who loves playing tricks on the new Pretties just as much as she does. When Shay runs away to join a group of renegade rebels living outside of the “normal” society, Tally is blackmailed to finding and betraying them before being allowed to become a Pretty herself.
What she finds there surprises her, and she decides she might want to make a life there for herself. That is until she accidentally betrays the community. This fast-paced read is the first of a series followed by Pretties, Specials and Extras, all of which we have on order!
