Why would someone with no Druidic training whatsoever even bother writing a book on the subject? Whatever the author's credentials may be, none of them have to do with Druidry at all. That is obvious in this book which is purely fabricated and must have come out of the imagination of one who practices Celtic flavoured Wicca and magick.
Sorry to dissapoint everyone, but celtic wicca, or made up systems that could fall into the catagory of celtic wicca has nothing to do with druidry.
It isn't that the material provided in the book won't work. They will, of course, just like any ritual or spell written up by any individual will... But it is misrepresented as Druidry. It is not. There are better books out there for that.
Most of the information the author offers in this book on druidry in made up. I have studied druidry for awhile now and thought this book was one of the worst i have come across. The book doesn't even make a very good drink coaster, so do NOT read this book.
