... The companion book can be purchased on Amazon, and is a bit pricey, but thank you Penthasilia for your opinion about the book! IMO, the card interpretations of the author, Michelle Belanger, are really quite wonderful. They are detailed, thought-provoking, and I actually find them very useful, unlike many other companion books.
What is so surprising to me is that I purchased the deck and book because of the connection to the Book of Enoch, and I was interested in the author's research and interpretation of this material. However, I have found that the deck also reads wonderfully for me, on a very practical level. It is now carried in my bag with my other favorites.
