World War Z: An Oral History of the Zombie War is a novel by Max Brooks.
Plot:
World War Z operates on the premise that 10 years after the decade-long Zombie World War, an agent of the United Nations Postwar Commission publishes a book with interviews he did with various key-figures in said war from around the world. This interviews do not make for one continuous narrative but paints a picture of the war through many little international mosaic pieces.
I didn’t think I would like World War Z as much as I did. Yes, I heard many good things about it, but I’m usually not really the person for political or military fiction, and this is both. But I’m glad to say that I fretted for nothing, because I really loved World War Z.
