This is the first in a triology.  A YA SF series in post-apocalypitic America in which everyone is controlled by some nefarious organization that makes everyone beautiful through surgery and let's them party themselves into stupidity.  Like creating generation of Paris Hiltons (but more attractive, I assume).  The heroine sort of figures out what's going on and gets drown into the underground and away from the weird, antiseptic completely controlled cities.  It's actually pretty interesting, though anvilicious in it's social commentary.  Westerfeld isn't a bad writer, either I might pick up some of his adult books.
