I can't speak as to the general accuracy of the majority of the contents of this book, but I can tell you that specifically in the case of Conway's entry for Freyja she informs us that one of her alternate names, Syr, means "seer." A simply Wikipedia search can tell you it means "sow." In addition, she erroneously claims Freyja was in charge of the Valkyries. With simple facts such as these not checked by the author or the editors and publisher, why would you trust anything else in the book? If you're a serious student of Wicca I suggest you don't even bother.
