Remember Tomorrow. James Axler

After twenty-first century America exploded in the chaos of a nuclear nightmare, a raw new landscape emerged, a world where death and dreams clash. Still, the best of the human spirit endures: the hope, the will to survive.But so does the worst: the greed, tyranny, the easy death. In his enduring odyssey across the hostile world called Deathlands, Ryan Cawdor is a warrior no enemy wants to cross.An earthquake in the Arkansas dust bowls leaves the companions for dead, until they are all reunited except for armorer J. B. Dix. Alive, though with no memory of the past, he is in the uncertain employ of the iron fisted ruler of a vital outpost along the routes that traverse the wastelands. Duma is the biggest, most dangerous ville in all of Deathlands, where jolt, jack, booze and sex are worth more than human life. Stalking Duma and preparing to attack this orgy of firepower is a crazed band of inbred worshipers of Nagasaki… and their unwilling new sec force led by Ryan Cawdor.
