What is the setting of the book Uglies?

The Rusty Ruins -a place where people from an earlier era lived than when people lived in the time setting of the book.

The Smoke-A place in the wild where runaway Uglies go to avoid the operation to become Pretties.

Uglyville-A town where children newborn to 11 are called "littlies", and children 12 to 15 are called "Uglies", and are separated from the "pretties" in New Pretty Town by a river.

Hope This Helps! :)
