Ravenous zombies have overrun the post-apocalyptic town of Desolation. Sharpshooter Luke and her older brother, Mark, are desperate. Their only hope is to track down and enlist the help of a gunman legendary in the western wasteland, a man known only as Lone. But if they find him, can they trust him? Cletus, a right geezer who claims to know Lone, seems to know more than he's saying—'specially after Luke mentions how the zombies are being controlled by a strange figure that bleeds yellow. And what are "Gunfathers," anyway? After fighting off radiation-twisted mutants for two weeks, Luke and Mark are ready for answers.
