This is the first full biography of Dion Fortune, one of the most striking personalities of the twentieth century. She hid behind a veil of secrecy and became a cult figure in the years after her death in 1947. A brilliant writer and pioneer psychologist, her whole life was devoted to living out an eternal myth in a story that can be told in terms of Virgins and Dragons, Moons and Oceans, and the spirit of the land itself. A powerful psychic and medium, obsessed with the study of magic, her career was never entirely within this world. And in her own eyes at least she was a Priestess, a channel for the Great Goddess, an exponent of the time-lost Mysteries of Women.
