I love the ambiance/feeling of fairy tale-like fantasy, but I've read so, so many retellings and I'd like to branch out! The only thing I can think of off the top of my head that might be like this was Nettle and Bone by T. Kingfisher, which literally read like a fairy tale but to my knowledge wasn't based on an actual one. I'm interested in things beyond strictly following the fairy tale formula like that as well!
