In our writing journey, many of us have found ourselves stuck with those pesky stories that turn out to long to be a short story and to short to be a novel. We try to cut, but then the story doesn't make sense. We try adding words, but the results are a work that drags. We are left with (publishing-wise) an unviable manuscript.
But do not despair. There is now a place for those poor homeless novellas -- the Miami University's Novella Contest. Now, they aren't specifically geared towards children's, but based on last year's winner, I think a YA stands a chance.
Break out those novellas. It would be nice if they could finally find a publishing home.
