In the seemingly picturesque Hudson Valley town of Black Spring, residents are haunted by the Black Rock Witch, a seventeenth century woman whose eyes and mouth have been sewn shut. Muzzled, the Black Rock Witch roams the streets, enters homes at will and stands beside the beds of children throughout the night.

To prevent the curse from spreading, the elders of Black Spring have quarantined the town by way of high-tech surveillance. Frustrated with being kept in lockdown, the town’s teenagers decide to break their strict regulations and go viral with the haunting. In doing so, they send the town spiraling into a witch-hunt that boils over into persecution, scapegoating and a shocking denouement.

Setting ancient magic against contemporary technology, HEX is one of the most thoughtful horror stories of the twenty-first century, made all the more chilling for its uncompromising view of humanity.
