A predator stalks a cold northern Minnesotan town. There is talk of wolves walking on two legs and attacking people in the deep woods. Lauren Westlake, resourceful and determined F.B.I Agent, has found a connection between the strange murders in the north and a case file almost a hundred years old. Traveling to the cold north, she begins an investigation that spirals deep into the darkness of mythology and nightmares. Filled with creatures of the night and an ancient romance, the revelation of who hunts beneath the moon is more grisly than anyone could have imagined.
