Science Fiction--Fantasy, Fantasy 

Saba has spent her whole life in Silverlake, a dried-up wasteland ravaged by constant sandstorms. The Wrecker civilization has long been destroyed, leaving only landfills for Saba and her family to scavenge from. That's fine by her, as long as her beloved twin brother Lugh is around. But when four cloaked horsemen capture Lugh, Saba's world is shattered, and she embarks on a quest to get him back.

Suddenly thrown into the lawless, ugly reality of the outside world, Saba discovers she is a fierce fighter, an unbeatable survivor, and a cunning opponent. Teamed up with a handsome daredevil named Jack and a gang of girl revolutionaries called the Free Hawks, Saba’s unrelenting search for Lugh stages a showdown that will change the course of her own civilization.
