I talk about how Franny and I played with the Moonology oracle deck last night and how wonderfully accurate the readings were.  I love this deck and I didn't expect to.  The artwork is far better than most decks and the simple definition on each card is enough to make the reading make sense to anyone.  The book with its deeper insight can help you add more depth to your reading, but the cards work fine without any extra input.  I really recommend this oracle deck, if you are in the market for one.
