Now, with five doors left on a cursed advent calendar and a demon named Zurvan orchestrating chaos across Marshport, the flames have finally caught up. His friends are dead. His wife believes him a liar. His son has been poisoned by demonic whispers. And as Christmas Eve draws near—the culmination of Zurvan's ancient celebration—Matt realizes the demon needs a new host. Someone close. Someone vulnerable.
