Go figure, right? A zombie novel with the theme of fear, could things get any more unoriginal? Actually, it could get way more unoriginal because Brooks truly does some interesting stuff with fear here. Unlike a low-grade horror novel about cheap fears and thrills, World War Z explores fear as its central theme. It addresses many different types of human fears—and not just the ho-hum zombie fear of being horrifically eaten alive. It also uses fear to springboard into an exploration of human nature and government. This way, fear becomes more than just boogity-boos that make you jump in the night. It becomes the scary-pants glue that binds all the novel's layers together.
