Official Description
The world of Uglies, set in our not-so-distant future, is a complex place filled with bubbly technology and lingo, yet bogus rules about status and appearance. That's why a guide to the world of uglies has been requisitioned from the hole in the wall. Inside you'll find:
A rundown on all the cliques, from Crims and Cutters to tech-heads and surge-monkeys
The complete history, starting with the destruction of the oil bug to the launch of Extras in space
How all those awesome gadgets came to be: hoverboards, eyescreens, skintennas, sneak suits...
PLUS an exclusive look at Scott Westerfeld's first draft of Extras -- starring Hiro, not Aya.
And so much more, it's mind-wrecking. [1]
