I got this book cheap from a second hand shop and in really glad I didn't spend much on it. As many have said, this is full of Wiccan junk and isn't all that useful for much else.
I'll grant a little forgiveness in that this book was published in the 90's, I think, and there wasn't really much available that wasn't at least heavily influenced by Wicca. That's actually still a problem in pagan literature in our current era, but at least we're moving away from the dogma attached to Wicca more recently.
There were so many problems with the information that it's difficult to figure out where to start on that. But, for example, the author gets so much wrong about The Morrigan that I wonder what research she did beyond a quick glance at the lore.
I don't recommend this book for any other reason except if you like to collect witchcraft and pagan books. It serves little use beyond that.
