Glastonbury Tor is the legendary resting place of the Holy Grail, but something else also rests beneath the hill
Glastonbury, legendary resting place of the Holy Grail, is a mysterious and haunting town.

Plans for a new motorway have intensified the old bitterness between the local people and the "pilgrims," so already the sacred air is soured. And, as the town becomes increasingly split by violence and death, Diane, local bookseller Juanita Carey, and the writer Joe Powys must now face up to the worst of all possibilities: the existence of an anti-Grail—the dark chalice.
