I have Gareth Knight books in my Amazon cart just begging me to pick at least one of them.
Knight's
A Practical Guide to Qabalistic Symbolism was one of my first esoteric tarot books back in the '70s. I never noticed what some people now consider his non-PC attitude. Its gabalistic content stood up well against Case, Regardie, Fortune, Bardon, Achad, (William) Gray, Wang, etc (but not Crowley, who was and is in a class by himself) that I was reading in the early days. I also bought
The Magical World of the Tarot but never did get all the way through it; I should give it another try.
Right now I'm reading two books:
Way of the Great Oracle by James Wanless for my Voyager Tarot study group, and Elizabeth Hazel's
The Tarot Decoded (excellent!) on my Kindle, which is perfect for reading while on an exercise bike. I've also been pecking away at DuQuette's Tarot of Ceremonial Magick, but the Enochian slant isn't doing much for me.
