I've been looking for years, trying to figure out if a book I think I read as a kid existed or not. It was a girl (I think a fairy) in a green dress and a blue cape, with dirty blonde hair in thick curls on the cover, and it had something to do with hiding a flute in a tree stump. I have no idea whether or not this is real, but I'm always on google trying to find out the name of the book.
I remember it was in a trilogy, the two other books having one girl in a pink dress with a horse, the other a blue dress with a basket. Do you have any idea what this book could be?
