The ghoul king

Summary/Review: "The Knight, Quinn, is down on his luck, and he travels to the very edge of the civilized world - whatever that means, any more - to restock his small but essential inventory. After fighting a series of gladiatorial bouts against the dead, he finds himself in the employ of a woman on a quest to find the secret to repairing her semi-functional robot. But the technological secret it guards may be one truth too many."--
