For 400 years, Earth has been a barren wasteland. The few humans that survive scrape together an existence in the cruel city of Pocatel - or go it alone in the wilderness beyond, filled with wandering spirits and wyrms. They don't last long. 13-year-old pickpocket Leandro and his sister Gabi do what they can to forge a life in Pocatel. The city does not take kindly to Cascabel like them - the descendants of those who worked the San Joaquin Valley for generations. When Gabi is caught stealing precious fruit from the Pocatelan elite, Leandro takes the fall. But his exile proves more than he ever could have imagined.
