World War Z

Origin
Max Brooks' World War Z is an apocalyptic horror novel, a collection of individual accounts brought together by an unnamed agent of the United Nations Postwar Commission. It follows the devastating global conflict against the zombie plague often referred to as African Rabies. The person accounts describe the resulting social, political, religious and environmental changes. The events in the book are told after the war but describes times before the plague, during the Great Panic, regrouping and eventually taking back the land lost to the undead.
