World War Z: An Oral History of the Zombie War

The Zombie War came unthinkably close to eradicating humanity. Max Brooks, driven by the urgency of preserving the acid-etched first-hand experiences of the survivors, traveled across the United States of America and throughout the world, from decimated cities that once teemed with upwards of thirty million souls to the most remote and inhospitable areas of the planet. He recorded the testimony of men, women, and sometimes children who came face-to-face with the living, or at least the undead, hell of that dreadful time. World War Z is the result. Never before have we had access to a document that so powerfully conveys the depth of fear and horror, and also the ineradicable spirit of resistance, that gripped human society through the plague years.

It’s a riff on "The Good War": An Oral History of World War II“. Each chapter is a self contained story, each has their own narrator. They’re good.
Make sure to get The Complete Edition! The original release was abridged. It was the pits!
