Ghostwalkers

Welcome to the Deadlands, where steely-eyed gunfighters rub shoulders with mad scientists and dark, unnatural forces. Where the Great Quake of 1868 has shattered California into a labyrinth of sea-flooded caverns...and a mysterious substance called "ghost rock" fuels exotic steampunk inventions as well as plenty of bloodshed and flying bullets. In Ghostwalkers, a gun-for-hire, literally haunted by his bloody past, comes to the struggling town of Paradise Falls, where he becomes embroiled in a deadly conflict between the besieged community and a diabolically brilliant alchemist who is building terrible new weapons of mass destruction...and an army of the living dead!
