I have mixed feelings about this, but it was worth reading. physically, it seems like a self-published book. I don't think it quite was, but it's a pretty small publisher and not all that physically appealing. the text was printed too close to the spine of the book, I had to try to open it really wide. but the font, the quality of the reproductions - even the author photo was low resolution. it just gave me a sort of background vibe of this information is kind of off the wall...
besides that, the contents didn't really live up to the title. I expected a lot of card meaning discussion, and there was that, but also maybe sort of the junctures at which you might use tarot. it was more like the author's personal collection of information. she started, oddly, with a comparison between the RWS and other tarot decks, which seemed to mostly say that by changing the artwork in other decks some of the pertinent jungian symbolism was abolished. anyway, considering the ugliness of the image reproduction in this publication, odd choice to include. then she goes into the jungian numerology of the suits, which was useful. her description of the court cards was probably the most useful. then she discusses all the major arcana with respect to the phase of development of the psyche that they describe. in this section she always puts, "if you stay in the phase of the hanged man too long, you become..." but she doesn't really give an indication of how you know you have been in a phase too long or how to know to move on to the next phase. and while the major arcana does trace the fool's journey of development, it's less helpful to understand this in sequence when you're looking at cards in a reading, which likely won't be in any such order.
at the end, she has a chapter about assigning astrological correspondences to the cards, which basically concludes with "don't, there isn't a way to do this". then she goes through the kabbalic tree of life, showing how to do a layout using the form of the tree of life as the spread. I personally don't care for kabbalah. it's not a system that clicks for me. and there are sample spreads, on the tree of life, the celtic cross, and one where she does 3 rounds of cards into the 12 astrological houses, which she also spends a chapter describing. the celtic cross reading makes a fair amount of sense, but the astrological one is pretty complex. so none of that bit was too useful for me, as I don't really like the celtic cross layout anyway.
it wasn't really what I thought it would be, but I did get some value from it, to sum up.
