A forgotten chamber secreted beneath a river.

An ancient evil that lies slumbering under the earth.

A guardian determined to fulfill his duty to his last, dying breath.

As something dark and deadly takes to the skies over Harrington Falls, Jake Caruso and his friends, Sam Travers and Katelynn Riley, find themselves drawn into a primeval conflict set in motion centuries before. As fresh blood is spilled and the death toll mounts, these three friends will find themselves faced with a terror beyond imagination, one that will require every vestige of their strength, faith, and determination to confront. Enlisting the aid of the local sheriff, the four of them will use the power of their friendship to face the Nightshade on its home ground in a last ditch effort to save their town from a fate it refuses to believe in.
