I second Promethea -- though it's strictly tarot from a Qabbalah/Crowley persepective. If you are interested in this system, there's really no better explanation available, IMO.
Scion said:The Piers Anthony books are patchy but catchy. Tarot is almost more of a structure and a point of reference in what is essentially his dramatized meditations on faith and metaphysics. They're entertaining, but a little thin, and shamelessly, blindly Waite-Smith oriented in terms of Tarot. Anthony tends to treat the WS as if it fell from the sky. You can tell he's not a reader, but there are times where he structures entire scenes around a facile keyword-y sense of the cards. Total pulp. Read these for breezy entertainment value.
