It was a longshot. not much to narrow down the search with but who knows. Don't suppose you remember any names? Characters, author, a word in the title?

Nothing. Maybe I only dreamed that I once read it.
Except, once I wrote music for a poem that I read and really liked, and years later discovered that the poem had long ago been set to music. And of course the old music was quite similar to "my" music.
