World War Z: An Oral History of the Zombie War by Max Brooks

This book purports to be an oral history of the zombie war. It's a really enjoyable account. The book does a good job of working its way through to cover the war fully despite being set up as a series of interviews. We don't get to know any of the individual characters terribly well (many of them just have one section), but overall it paints a compelling and exciting portrait of humanity in crisis.
