This book gives the impression that it's been cobbled together in order to make money. The author uses cards from several different packs and gives her own interpretations, with a few "green" and "pagan" comments added....well,this is entitled Tarot for the GREEN Witch.
Half of the book consists of cross references : ""8W/QC News from a distance about language skills/insight/determined swift action"; "Moon/2W Earned success/fulfillment from trusting instincts/manifesting subconscious". You get the idea? Very "tarot by numbers".
If you're a reader already, you certainly won't need this. If you're thinking of learning, get a book that teaches YOU to READ, not repeat someone else's ideas by rote.
If you're looking for a good, green, earth based, British pagan tarot set, check out the Sacred Circle tarot, one of the packs this author uses. The black and white pictures given here don't do the pack justice, and neither do the small coloured pictures on the book's cover. The Major Arcana in the Sacred Circle Tarot is a work of art in it's own right. The book that comes with the pack is excellent. Check it out.
