Be Greg's editor for a day.
A fair amount of the fiction I've written has been "We need something that shows off this element of the setting, it needs to have a big betrayal of trust, and, also, a monkey." Editors and publishers get to do this -- set parameters for fiction writers who then, like chefs with limited ingredients, try to produce a delicious meal.
If this ransom clears, I'll write a short story (probably 2-5,000 words) and release it for free through my trusty internet library. But if won't just be ANY story. If you pledge $50+, you can dictate ONE element that must be present. I'll limit that by saying no fanfiction, but stuff in my established settings -- eCollapse, Milonda, PROGENITOR -- are all fair game. (I'll just have to hope and pray there's no crossover.) Or maybe you want a love story. Or a revenge drama. Or for someone to get caught in flagrante delecto with the babysitter. You name it, I'll do my best to put it in there.
Will it be a hilarious mess, or an exquisite corpse? Only the high rollers get to decide.
