Except the poets and the novelists aren't expected to have finished products at month's end. A story would have to be completely finished, wouldn't it? And though I've written many stories in under a month, it always seems like six months later I have a flash of inspiration and go change them. Maybe that's just me.
There are a lot of good short stories out there. A lot of great ones. But here are three of my favorites, all web-accessible published by Willow Springs.
"The Receiving Tower" by Matt Bell
"Sin-Tra-La!" by Diane Lefer
"Sine Die" by Sarah Hulse
