The notes in the back of the 20th anniversary edition make this a five star read. This book is clearly a living work, which the author has returned to and worked and worked until a represents a full journey. While everything in this is not for everyone (it's Wiccan-based), it is a great primer in some of the history of modern witchcraft traditions. If you're interested in the goddess, this is also a great resource for basic incantations, chants, rituals, and meditations.
