Subspecies is the story of two vampire brothers. Stefan, the “good” vampire, was brought up as royalty in a kingdom of kindly vampires who used servants to quench their bloodthirst, but never killed them by drinking too much. Radu, his demonic brother, was sired when a demon tricked Stefan’s father into bed by pretending to be his wife. The demon revealed her true form after their mating, and went on to give birth to a nightmare being bent on conquest of the vampire kingdom. Subspecies is the story of the two brothers’ eternal rivalry, and the human lives that are destroyed in the conflict.
