I've bought this book having heard good recommendations on Eden Gray's books and having read the cards (using the Rider deck) for over a year.
Each minor arcana cards is explained in two pages-one with the card's picture, and another containing mainly white space, half a dozen lines that describe the card and shed a *bit* of light on it's meaning, and six lines to explain it's meaning upright & reversed usually with a few keywords.
This will pass for someone who just wants to start quickly, but is shallow. The extensive fillers (why give a whole page for each card's picture ? the reader is supposed to have the deck at hand and a verbal explanation is included. They could at least put the picture and text on the same page, as in 'Mastering the Tarot').
In contrast, the major arcana are well explained, and the glossary of terms is a small gem. I think those two sections do an excellent job of getting a newcomer on track quickly.
The two spreads explained - each with an example - are as good as the major arcana section, though I think that the Tree of Life spread could be replaced with a spread more appropriate for newcomers.
All in all I think this book is good for people with no knowledge of the tarot who want to *start* reading with a deck quickly and painlessly.
But I think that for anyone who wants to go beyond the very basics should start with a better book, e.g. Joan Bunning's Learning the Tarot, rather than this book.
