Query: Unca Bucky's Big Blue Book

I actually recommend this one to my students with the caveat that he is teaching his particular path of Seax-Wicca. He has some excellent parts to his book as well as some that may make you giggle. I have to admit that the foil helmet of the God caused me to laugh until I cried. Overall, it is a book I think needs to be on your bookshelf if you wish to learn about Wicca and Witchcraft as well.
