Fear is abroad in the Deadlands as a string of brutal killings and cattle mutilations trouble a frontier town in the Arizona Territory, nestled in the forbidding shadow of the rugged Thunder Mountains. A mule train is massacred, homes and ranches are attacked, and men and women are stalked and butchered by bestial killers who seem to be neither human nor animal. Meanwhile, a ruthless land baron tries to buy up all the surrounding territory and possibly bring about an apocalypse.Once an officer in the Union Army, Tucker Bringloe is now a worthless drunk begging for free drinks at the corner saloon. When he's roped into a posse searching for the nameless killers, Tuck must rediscover the man he once was if he's to halt the bloodshed and stop occult forces from unleashing Hell on Earth... when the Thunder Moon rises.
