An unknown invader – code name GRAY WOLF – commandeers a nuclear missile silo in North Dakota and threatens to launch a Minuteman III ICMB. The President’s only containment option is to obliterate the Midwest nuclear arsenal at a cost of millions of civilian lives. Across the country in Key West, the world-renowned forensic sleuth Dr. Elliott Sumner is pulled into the international crisis moments after he spots a serial killer he put away for life. Elliott gets the call to examine hideously mutilated corpses found frozen solid in the wilderness. The macabre blood trail is the only way to identify GRAY WOLF and give the President more options. Setting aside a life-threatening condition, Sumner goes to North Dakota. Can Elliott solve the grisly international forensic puzzle, or will time run out? Can the launch of a rogue Minuteman III missile into the world be averted, or is a nuclear Armageddon the only outcome for the unimaginable terminal breach?
