Given how popular fairies always are, as well as ABC books, I’m surprised this hasn’t been done before.  It had a good variety of words for the alphabet, selecting from a wide range of fairy lore, each accompanied by a rhyming quartet, just enough to give a touch of explanation, and perhaps encourage enthusiasts to seek further information. The illustrations are charmingly drawn, including a human boy and girl and three fairies that continue throughout the book, along with page-specific illustrations that are supportive of the text.  My one criticism of the book, keeping it from earning an R* rating, is that there’s something jarring about the color-scheme used in the illustrations – too many clashing colors are visually off-putting.
