Post Apocalyptic Science Fiction Books

The defining element of Post Apocalyptic fiction is that takes place after an apocalypse. This time can be anything from right after (though Apocalyptic Science fiction can often cover events right after an apocalypse too) to a long period of time in which the dust has settled and a new world has been shaped. Most post-apocalyptic fiction opt for the later and usually focus on a group of survivors eking out an existence in this changed world (usually changed for the worse).
