I had this idea today... the setting is a post-apocalyptic world that has been destroyed by something along the lines of nuclear bombs, giving people powers. These people use their powers for survival, evil, and good. The main character would originally use her powers to keep herself and her family alive, but would start to help others with her powers. Eventually she goes on a sort of mission to eradicate the people using their powers for evil. Idk exactly, it's still a rough idea. But what do you think??
