For decades, a pack of werewolves has dwelt undetected among the populace of a typical northern Ontario mining town. The abominations exacted a tribute which was resentfully paid on the zenith of every full moon. A critical event exposes the presence of these stygian creatures. After a ten-year-old child is brutally murdered and devoured, the villagers cry out for help. Bryan Boyd, a werewolf slayer of known repute, answers the call. Well aware of the tenacity and exceptional abilities of this unusual man, the dark beasts decide to flee—all except one, who chooses to stay and fight. Troy Larson is the first to fall. His mate is slain shortly thereafter. Subsequently, the adventure begins. Bryan sets off on a mission to hunt down and terminate the remaining members of the pack. The quest proves to be lengthy, perilous, and saturated with surprises.
