I partook of the weekly Flash Fiction Challenge over at Absolute Write
last night. The basic idea is that you are given a randomly-chosen prompt (usually just a word or two). Once you know the prompt you have 90 minutes to write, polish, and post it to a password-protect area of the forum.
It's a fun exercise, one I use occasionally to experiment with different styles or ideas. There's even a market for flash fiction
My story this week, Holy Nepotism, was a rousing success. So well, in fact, that I'm looking for a market to send it to. It's a humor piece coming in at 327 words. I suppose you could say it has a slight religious theme, since it takes place in heaven, but it's not religious per se.
