I understand that D.J. Conway is a highly popular author in the Llewellyn stable, however, I don't think she could research her way out of a paper bag.
I used to own a metaphysical bookstore, and was very dissapointed when this book came out. I was hoping for a well-researched and documented work on the Goddess, and found instead a book filled with incomplete information.
The author didn't take much time to research her subject. This is patently obvious when she makes the statement that there are no surviving Goddess traditions in African religion. This is a patent fallacy; a not very close look at West African traditions will reveal not only a surviving tradition of female Divinity, but a thriving tradition that spread with the African diaspora to the Americas, and the Carribean during the slave trade.
If you want a serious book about the Goddess, do yourself a favor and buy Janet and Stewart Farrar's book, "The Witches' Goddess." That book is well-written, interesting to read, with solid research behind it. Another excellent book on the subject is Patricia Monaghan's "The New Book of Goddesses and Heroines." This book is also well-researched and written in an engaging, lively style.
