The greats of fiction Stephen King and George R. R. Martin lead the fanfare for Hex, so be assured that Thomas Olde Heuvelt’s debut English novel is both terrifying and unputdownable in equal measure.

Whoever is born here, is doomed to stay until death. Whoever comes to stay, never leaves.

Welcome to Black Spring, the seemingly picturesque Hudson Valley town haunted by the Black Rock Witch, a seventeenth-century woman whose eyes and mouth are sewn shut. Blind and silenced, she walks the streets and enters homes at will. She stands next to children’s beds for nights on end. So accustomed to her have the townsfolk become that they often forget she’s there. Or what a threat she poses. Because if the stitches are ever cut open, the story goes, the whole town will die.

The curse must not be allowed to spread. The elders of Black Spring have used high-tech surveillance to quarantine the town. Frustrated with being kept in lockdown, the town’s teenagers decide to break the strict regulations and go viral with the haunting. But, in so doing, they send the town spiraling into a dark nightmare.
