Sojourners — P.M. Griffin

An afterlife mixup sends a good man to HellWhen Peter ends up in that long tunnel and endures a review of his life, he's slated to go to Paradise. Instead, the afterlife machinery reverses, spitting him out into a wasteland of scrub brush and darkness.This is not ParadiseIn fact, the residents call it HellReduced to Stone Age technology, Peter and the last remaining humans struggle to survive against hellhounds and monster men. Beyond an uncrossable sea lies what appears to be a sunlit realm of fruit trees and birds, taunting them in their darkness and deprivation.Peter's only hope of reaching that place would be the legendary Sleepers, warriors lying in state a mile beneath the mountains. The network of caves is guarded by a murderous phantasm, though, and she hungers for vengeance. To plumb the mountain's heart and free the captives, Peter will have to fight the most devastating creature Hell has to offer.
