Disturbingly mutilated dead animals are being found in the mountains of Alaska and hunting parties are disappearing. There is something evil at work here and law enforcement has put a name to it. Anubis.
Roy Bohannon is a man without a past. He finds himself fleeing through the Alaskan wilderness. Someone is trying to kill him. Why? He can't remember who's chasing him or what he's done. He can't remember where he's been or even where he is now. What's happened to him? And is his name really Roy Bohannon?
He stumbles into a cabin with a mummified man. A man he knows. Who killed him? How? Bohannon talked to him only two days ago. When he's confronted by armed men, he flees again and finds sanctuary in a small village, but runs afoul of the local law and winds up in jail. He suspects that the only way he's going to get answers is to go to the source of Anubis in the mountains.
And what's happened to Florida detective Bone Ramsey? No one has heard from him in weeks. Where is he? His free-spirited squad of mercenaries decide to take matters into their own hands and find him. They rescue Bohannon and soon find themselves on a fast paced odyssey which involves a firefight with a helicopter gunship, and chasing a mad man through a nightmarish world of fierce monsters and savage alien warriors.
