Saw an interesting question on Reddit that I wanted to run by you brilliant folks here: What are your favorite lesser known works from well known authors?
Good question and a bit of a struggle to really think of some.
First one that comes to mind would be Peter S Beagle's The Folk of the Air, which is kind of a slice of life that falls slowly into magic and gods, featuring Joe Farrell, a recurring character from his short stories. (Though this is easy for Beagle, as anything that isn't The Last Unicorn is lesser known to the point of no one knowing.)
