Dark Sanity - Paul L Centeno - Bog

Set in the fifty-fourth century, the story focuses on Flint Cross, a gunslinger ripped from his roots in the Wild West and placed into the desolation of post-apocalyptic Australia. Plagued with amnesia and nightmares, he finds himself lost and on the brink of madness, doomed to forever wander an empty realm of war-torn souls.
But with the very fate of the universe in Flint's hands, the ancient forces of the aboriginal dreamtime are his only hope. Through seemingly endless experimentation, he must learn to recover his lost memories, raise an army, and construct a steam-powered, interstellar starship to locate and take down his enemy-all while working against the clock and resisting the slowly creeping insanity that threatens to keep him lost forever.
