Im looking for a childhood book that I used to love?

I know that "The Wild Swans" (stinging nettles) is by Hans Christian Andersen, and that "Rapunzel" is by the brothers Grimm, and that the Greek king of legend is Midas. Because these stories are from such different sources and have been published so very many times over the years, it would be almost impossible to know precisely which book you have in mind. However, if it definitely WAS a Reader's Digest children's book, then it might have a title incorporating the likes of "Compendium of ..." or "Treasury of ..." or "World's Best ...". etc. So it might be an idea to search for it with keywords like that, plus "fairy tales", "children's", "stories" and so on. Good luck in finding your cherished book!
