The Twelve Maidens - Stewart Farrar - Bog

At the pinnacle of Maiden Tor, a coven of witches gather within the Twelve Maidens, a Neolithic stone circle. Below, in the English Countryside, a new radar project is meeting with success -- until the scientists begin dying. Margaret Govan sensed the evil in the place and knew that something needed to be done. With nowhere else to turn, the scientists enlist the help of a coven of white witches. What follows is an exciting battle between the forces of good and evil, but only one coven can the Twelve Maidens.
