This book is from a family witch - a Wiccan witch, that is. And not in the true sense of "historical" no, it isn't. And the "Chaos magic" in it is from the "other orders" he himself said he was a part of. He's trying to be another Wiccan Gardner, and it's just annoying. This isn't much at all, and I was very dissapointed as it is yet ANOTHER repitition of other sources. It's wiccan, and he should just admit that. There's no shame in it, it's as mainstream as anything else, it's just not pre-christian religion, at all.
The book is not very original in content, compiling material from a variety of Wiccan, folklore and Chaos Magic sources - but it is enthusiastic and sometimes engaging. The most cunning thing about the author Nathaniel Harris is his description of himself as a 'hereditary witch'; in fact his mother and stepfather are Alexandrian Wiccans, which is not quite so exciting.
