The Durham brothers own a farm in the Smoky Mountains where they raise Thoroughbred horses. After ten years of coexisting in the mountains with the local vampire, relations between the brothers and the bloodsucker begin to go south. The vampire wants the shifters off "his" mountain, and he will stop at nothing to convince them to leave. As the three brothers meet their mates, fear for their safety increases. Each book in the series follows one brother's mating and subsequent encounters with the increasingly powerful vampire.
