In a game of cat and mouse extending from the frozen waters of the Chesapeake Bay to Santa’s home base at the North Pole, immortal Hamelin Russell battles the vengeful son of a powerful demon who will stop at nothing until he destroys Hamelin and all that he holds dear. Before Christmas Day ends, Santa Claus, an Anacostia Delta musician, and a young boy will be caught in the crossfire. One will die, one will become possessed, and the third will be saved by a simple act of human compassion. Only Hamelin can end the rampage. There is just one problem—the solution goes against every tenet of the soul runner’s ancient honor code.
