Beginning to work together in London in the 1970s, they wrote and published "The Western Way" in 1985. This followed the lead of Christine Hartley's "The Western Mysteries Tradition" (1968) by identifying and promoting a European mystical tradition to offset the then-current domination of Eastern mysticisms from India and China. The book included meditations to enable readers to make contact with their inner worlds. Historian Ronald Hutton considers this an influential work. They also edited "The Encyclopedia of Celtic Wisdom" (2000), devised the Storyworld series (2009ff) and, most recently, created "The Steampunk Tarot: Gods of the Machine" (2012).
