When the night things of Courtney's community start causing trouble, it's up to the girl to find out why. The coven blames the hobgoblin initially but quickly turns its ire to Skarrow, a night thing in service to the town's most reclusive witch. Uncle Aloysius doesn't believe the disturbances are that easy to explain. His dismissal of the Coven's alleged culprit starts Courtney down a twisted path that leads to the true mastermind behind all the horror! But does Courtney stand a chance against a being that powerful and manipulative?
