What would you do if you slept through the apocalypse? What if everything you knew about disaster survival came from old B-movies? What would you do if society as you know it suddenly became The Oblivion Society? After an accidental nuclear war reduces civilization to a smoldering ruin, grocery clerk Vivian Gray joins a comically inept bunch of twentysomething survivors, and together they try to ride out Armageddon on little more than scavenged junk food and half-remembered pop culture. When the contaminated atmosphere unleashes a menagerie of deadly atomic mutants, Vivian and her friends take to the interstate for a madcap cross-country road trip toward a distant sanctuary that may not, in the strictest sense of the word, exist. But can they get to safety before the toxins get to them?
