She has developed the innovative add-on to Cosmic Pattern's Sirius: Who Wins, which captures the rules of Bonatti for warfare for use in researching the outcome of sporting events. Her Learning with Lee cd series on learning classical astrology methods provides timeless techniques in the latest technical format.
