When the apocalypse broke out, Gabriel was desperate to save his sister. But she was nowhere to be found. After searching relentlessly, he learns she’s being held in the seedy underbelly of Lowtown, a newly formed stronghold of humanity. Enraged by what she’s been forced to endure, he’ll do anything to get her back from the men who enslave her. Even if it means igniting a war. Unfortunately, she’s not the same girl he left. She’s different. Angry. Brazen. And all too eager to remind him they’re not blood related.
