Ashes on a Distant Wind

Before the Vrete came to Earth, Donovan Riggs was a man of faith. Now they're gone, and he's left that part of himself behind for good. In the ruinous aftermath of a war nobody won, he is simply trying to survive. With Beau Greer-a young medic who stumbled into his life and then refused to leave-Riggs travels dangerous roads between long-dead cities. Scavenging doesn't offer much of a future. It barely provides for the present.
But Riggs will do anything to protect what's his.
