When I was younger, I had quite an old book. I think it was a collection of short stories, but they were all pretty similar so ran into one another in my head! It was kind of like weird fairy tales - often things happened like someone sank to the bottom of a well and ended up in a meadow of grass, or climbed up a big glass mountain - that sort of odd thing! There were also frequent mentions of ravens, addressed as 'bird of ill omen.' In my version I think it had a green cover.
Is this vague description by any chance ringing a bell for anyone?
Thanks for any and all help!
