I had a book of so-called modern fairy tales that were written by popular authors of the day. The book was published in the early to mid 90s, and I bought it from the Sci-fi book club. Some of the stories were silly, some were fantastical, and others were darker. It was probably close to 1000 pages, as I remember it being a thick hardcover.
I would really love to find this book again, as there were two stories in it I absolutely loved, and my copy of the book was ultimately destroyed in a flood.
ETA: One story was a very serious one, involving a young man, possibly a dwarf or similar, that was helping a princess. I think it was a princess, anyway. One passage I remember because it struck me was about how a cook took pity on him and regularly gave him pieces of sausage that had just about gone bad along with stale bread that was still good to eat, but not the nicest to eat.
Another story dealt with children in the present time being taken by fairies (maybe only one child) during the night, possibly as part of a dream. I cannot remember more of this story, but I enjoyed it.
I am remembering a third story that was completely irreverent, making fun of knights saving princesses, in some ways making it sound like high society California transported to a land oof knights and princesses. I think they had some sort of scoring system for knights.
