Exit Kingdom - Alden Bell

In a world where the undead outnumber the living, Moses Todd roams the post-apocalyptic plains of America. His reprobate brother, Abraham — his only companion — has known little else. Together, they journey because they have to; because they have nowhere to go, and no one to answer to other than themselves.

Traveling the bloody wastelands of this ruined world, Moses is looking for a kernel of truth, and a reason to keep going. And a chance encounter presents him with the Vestal Amata, a beguiling and mysterious woman who may hold the key to salvation. But he is not the only one seeking the Vestal. For the Vestal has a gift: a gift that might help save what is left of humanity. And it may take everything he has to free her from the clutches of those who most desire her.
