Book excerpt: "The Walking Dead" is both a hugely successful comics series and a popular TV show. This epic story of a zombie apocalypse is unique. It focuses on the long-term individual, social, and moral consequences of survival by small groups of humans in a world overrun by infected zombies. Guns, chainsaws, and machetes are not enough for survival: humans also need agreement on rules of conduct. Can equality or fairness have any polace in the post-apocalyptic world? Do theft or even assault and murder become okay under desperate circumstances? Who should be recognized as having political authority? What about eating human flesh? Should survivors have children?
