Harry Jordan is the latest in the defenders of the Earth from aliens. He's off to a rocky start, and not really what people would think of as defender material, but if he could survive his first hour on the job, he might turn the war around.
Or he might just crash and burn.
(This story was inspired by Stray Cat Strut by Raven's Dagger and Magical Girl Gunslinger by Mikasame. They are good stories about wars for the end of the world against invaders.)
