MOON MAGIC is one of several fascinating and beautiful novels written by the renowned Esotericist and Psychologist, Violet Mary Firth, better known to the world as Dion Fortune. Fortune, notorious for her use of the novel format as a vehicle for conveying complex and highly controversial esoteric (and often overtly pagan) secrets, struck pure gold with MOON MAGIC. In the author's own words, "... there are some very curious things if you read between the lines. Writers will put things into a novel that they daren't put in sober prose, where you have to dot the I's and cross the T's." (see THE GOAT FOOT GOD).
On the surface, MOON MAGIC tells the story of a lonely, yet privileged man. A renowned doctor and professor of medicine, he has an uncanny ability to diagnose illness but lacks in capacity to heal. He is trapped in a failed marriage, disliked by associates, students and patients alike for his brusque demeanor and his utter lack of etiquette and social skill. In short, the good Doctor has no bedside manner. With the aid of Lilith Le Fay (last seen in THE SEA PRIESTESS as Vivien Le Fay Morgan), he embarks on a perilous journey toward spiritual enlightenment. Lilith, a thoroughly modern woman trapped in a Victorian world, serves the role of "Initiatrix", as the modern incarnation of the veiled Isis, as Adept and pagan priestess in a re-enactment of ancient rituals designed to free the good Doctor from the jail forged by his own karma. And in the process, Lilith herself achieves transcendence. This novel has everything to make it sell to a modern audience - mystery, action, and even eroticism. But at a deeper level, MOON MAGIC represents a primer for the seeker looking to reclaim lost spiritual knowledge - a "How To" guide that quite eloquently reveals some of the ancient arcane secrets and practices long held sacred by Western secret societies and mystical orders.
MOON MAGIC is an amazing achievement. First, it is quite remarkable that a woman in post WW-I England authored this controversial and thought-provoking novel and succeeded in getting it published. What is nearly unfathomable, however, is that MOON MAGIC, like it's prequel THE SEA PRIETESS, was written at a time when the witchcraft statues still existed on the books in England. Engaging, and deeply philosophical, MOON MAGIC holds value for even the casual seeker of enlightenment. In addition, the book is well written and entertaining. When read with it's companion novel, THE SEA PRIESTESS, the alchemical prerogative is complete. Approach this book like you would approach the Philosopher's Stone. There is much to learn here, but apply what you learn with care. As Fortune reminds us, Nature can destroy as well as create.
