In a frozen Arctic wasteland, an ancient legend lies dormant under three thousand years of snow and ice, while half a world away a Christmas Eve Nor'easter pummels Eerie Cove, Massachusetts. Joshua 'Doc' Lavine is an accomplished Boston neurosurgeon but he faces a career-ending lawsuit and the threat of criminal charges. No one feels sorry for him because his surgical skills are second only to his misanthropy, and while news of Aunt Sadie's death should be a welcome diversion, it revives memories of ancient rituals and court documents that were sealed when Doc was thirteen. A fresh body has been found inside the house Sadie bequeathed to Doc, and when FBI Agent Quinn Masterson arrives in Eerie Cove asking questions, Doc realizes that his time is running out. Once determined never to return to that house, Doc now knows he has no choice. Trapped inside the house on Christmas Eve, the truth will be revealed: a clandestine organization linked to Nazi Germany; an ancient legend frozen in time; pagan graveyard rituals performed in the still of night; and the truth about Doc's horrifying past.
