"At last, a comprehensive biography of Dion Fortune, based upon the activities of the Society of the Inner Light. Much comes to light that has never before been revealed, including her early experiments in trance mediumship; her first contact with the Masters; how she and her husband befriended the young Israel Regardie; her hitherto unknown "occult police work," which brought her into unlikely contact with occultists such as Aleister Crowley; and her continued contacts since her death."
