Blood Red Road by Moira Young
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 a monster sandstorm arrives bearing four cloaked horsemen, Saba's world is shattered. Lugh is captured, and Saba embarks on a quest to get him back.
Suddenly thrown into the lawless, ugly reality of the world outside of desolate Silverlake, Saba is lost without Lugh to guide her. So perhaps the most surprising thing of all is what Saba learns about herself: she's a fierce fighter, an unbeatable survivor, and a cunning opponent. And she has the power to take down a corrupt society from the inside. Teamed up with a handsome daredevil named Jack and a gang of girl revolutionaries called the Free Hawks, Saba stages a showdown that will change the course of her own civilization.
