Description[]
Inside the house, a group of childhood friends gathered for a Christmas party. Outside, the blizzard began, a howling hell no human could survive. But what lurked in the storm was not human. It was a mutant thing with a ravenous appetite for human flesh--and an insatiable lust for hot, fresh blood.
