It's 1913. Rosemary and Aaron Harker, sister and brother, are Huntsmen. Their blood isn't entirely human, and they have the ability to hunt and kill the Uncanny, unnatural creatures of the night who sometimes hunt humans.
The Uncanny don't hunt humans often, because of the Huntsmen. When they do, the Huntsmen respond, and kill the offender against a long, uneasy truce. The Huntsmen don't try to wipe out the Uncanny, because there are too many of them, and humanity would be the losers.
Rosemary and Aaron receive a letter, telling them a distant cousin, knowledgeable about the Huntsmen but not quite one himself, has died. He left a note saying that if he died in unusual circumstances, Rosemary and Aaron should be summoned. They quickly pack and leave, with their hound, Botheration, for a small town in upstate New York.
