Four families. One house. An ancient fiend scheming to devour them all.

Learning the truth of a mysterious home their families have shared for years, four bloodlines come face to face with a frightening reality that soon leaves them haunted—and hunted. A sinister force brews in the spaces between these walls, and hell will rise if ever he's allowed to have his way.

Darkness climbing. No escape in sight. The Helm, an ancient relic imbued with power, might just be their ticket to salvation...until its eldritch forces backfire, digging them deeper into the grasp of the enemy. Treachery looms as evil weaves its way into the minds of the vulnerable. And while the menace seeks to divide and conquer, families are forced to sever old bonds and sacrifice whatever—or whoever—they must to survive.

Now, plunged into the heart of evil and strapped for time, embattled bloodlines seek and gather every magical defense they can acquire to stall the advance of their infernal adversary into the realms of man. But like them, their enemy is not alone, and his underlings are just as bloodthirsty as him.
