Gideon, a half-breed mutant with a surly temper and rotten luck, struggles to scrape a living as a tracker in the desolate territory near the gateway to the human world. Business seems to be picking up when Gideon is approached by a powerful dark elf with deep pockets and a serious problem. Human miners at the dark elf's plant are being taken by an elusive predator. Gideon is pressured to find the killer before word of the disappearances reaches the human world, endangering the tense relationship between their two races. But, nothing is simple this close to the conduit between worlds. Archangel, a ruthless mercenary operating in the secret sectors of mutant society, has set his own deadly game in motion. Surrounded by savage wilderness and cut off from contact with civilization, Gideon must find a way to protect his friends and survive to collect his bounty.
