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, Leando takes the fall. But his exile proves more than he ever could have imagined — far from a simple banishment, his consciousness is placed inside an ancient drone and left to fend on its own. But beyond the walls of Pocatel lie other alebrijes like Leandro who seek for a better world — as well as mutant monsters, wasteland pirates, a hidden oasis, and the truth.

From Donna Barba Higuera, Newbery and Pura Belpré Medal-winning author of The Last Cuentista, comes another novel to astonish us and create a whole new imaginative world, that holds a mirror to our own.
