When a cosmic radiation storm hit the earth in the fifties, initially no one knew what happened. When a mutated race of humans was born in the seventies as a result of the storm, it was hard on everyone but hardly the end of the world. That came in 2013, when the authors of the radiation storm returned to reclaim what they'd left and everything else besides. What stands between alien invaders and life as everyone knows it are the uncertain convictions and tentative alliance between the two races sharing the Earth.
I'm posting on March 12th, and I'd need the story back by Monday the 11th at the latest so I could integrate any necessary changes.
Thanks much! :)
