Fiction is Stranger Than Truth

World War Z by Max Brooks (son of Mel) is a compelling, horrifying account of how humanity is almost wiped out by a zombie plague. The story unfolds as a series of newspaper-style reports and interviews with the survivors. Starting with the doctor who discovers the original outbreak in China, the narrator crosses the world talking to soldiers, politicians, black-marketeers and others who played their part in the war. The result is an unusually well-written horror story, made all the more believable by the non-fiction structure of the narration.
Clearly fiction, I was more than a little surprised (but highly amused) when, browsing in one of my local bookstores, I found it prouddly displayed in the non-fiction section under History.
Then again, maybe there was a zombie outbreak and I missed it.
Did I?
