Extras, the final book in the Uglies series, is set a couple of years after the mind-rain, a few earth-shattering months in which the whole world woke up. The cure has spread from city to city, and the pretty regime that kept humanity in a state of bubbleheadedness has ended. Boundless human creativity, new technologies, and old dangers have been unleashed upon the world. Culture is splintering, the cities becoming radically different from each other as each makes its own way into this strange and unpredictable future . . .
