Rachael Pollack writes the best books on Tarot. She is highly educated and knowledgeable with a fascinating personal life (google her and see). She wrote two books called 78 degrees of freedom, parts one and two, that look at each card in detail, discusses the history and some of the psychology of tarot, and shows three kind of spread. From other books I have read it appears these two books revolutionized Tarot reading for the creativity and insight she brings to it.
This is a review for part two, which has the minor arcana cards and the spreads, and the only reason I give it four stars is because both books are now available in a singe volume called Seventy Eight Degrees of Freedom, A Book of Tarot. That I gave five stars.
