Not a faeries book for kids - but very interesting. There is a fundamental notion here, not really addressed in the book, that fairy-tales are some form of "code" carrying very old folk tales and mythology through the dark ages and into the modern age. Could go with a lot more exegesis and color, but if you are interested in folk tales, this is useful.
