I’m guessing it was from the 70s or 80s, maybe earlier. softcover, fairly thin, and beautiful uncolored illustrations inside. From memory, it was about a girl who lived out of an old single carriage (starts with an illustration of her standing next to it) and traveled, with short stories of her adventures.

The one I remember best is her going to three towns, singing in one and being told singing is banned because a dragon took the towns best singer, dancing in another town and being told the same, and (I believe) telling a story in the third town? Later on, she finds the dragons cave where he has the three stolen girls in his stomach, and from the best of my memory, the three girls in his stomach tell him a story and sing him to sleep, then dance in his stomach until they’re spit up, and the main character saves them? I perfectly remember there’s an illustration at this part with all 4 girls escaping on a horse together, and I used to stare at that page for so long.

Later on in the book, all I can seem to remember is another point where she’s in a forest and meets some kind of shapeshifter / kelpie or similar creature… but that’s all I’ve got. I believe the girl is on the cover, and I seem to remember the cover art being very neutral/earth toned. I re-found this book on amazon years ago, but now I can’t find it again and cannot for the life of me remember the title or author. It was my absolute favorite book and i’d love to be able to find it again.
