A short story of mine has grown until it's become a bit of a monster - about 15K. I don't know if that makes it a novelette or a novella, but it's certainly too long for most of the journals I would normally consider for submission.
A superstitious dread of talking too much about my work before it's published prevents me from going into too much detail. But I can say that the story is told from an unusual perspective, that the setting is historical, and it's definitely non-realist (although it isn't genre fantasy or magical realism, either).
What would be a good market for experimental novellas? I tend to prefer print, but for this awkwardly-sized piece I'd (reluctantly) consider an ebook publisher.
