I just polished and submitted the longest short work I've penned to date: "Ranching the Sleore" (a "novelette" of about 8,400 words). Let's just say it involves various bodily violations.
It is probably the foulest story I've written.
I felt physically uncomfortable putting some of those words on paper.
There are only a handful of markets for such a thing.
What the f$#&! was I thinking?
(but "novelette" is a cute word, huh?)
