I prefer science fiction, fantasy, and horror without the spaceships, dragons, and zombies.
To help you with your Short Story Month celebrations, here are some FREE shorts you may wish to check out with your eyeballs and brain parts:
"The Steel Valentine," by Joe R Lansdale (Free at Amazon)
"A Town Called Hatred," by James Newman (Free to read online)
"Specimen 313," by Jeff Strand (Free at Amazon)
Also, if you're kind of bored, you can check out what short stories I've read so far this month at my blog.
