I wrote a short story for a contest, and it turned out really good IMO. It is only 5000 words long, but it is filled to the brim with action packed awesomeness, and it feels longer, or more condensed than the average story of its length.
"Trouble stirs in a secret military base when three mysterious mercenaries make off with a truckload of experimental conventional missiles. Officer McDowell is quick to pursue the thieves, but he soon learns that their missile heist is not all it may seem." - Description on fictionpress.com
So, here's the link. Review if you have the time, but no pressure. It's well worth your while!
Enjoy.
