The Zombie Survival Guide by Max Brooks
I'm not quite sure what genre this book fits into. Mockumentary is the first word that comes to mind but in a book form. It's quite well written, it conveys the whole zombie scenario in a very believable manner. I originally thought the book would be quite tongue in cheek but it's written more as deadpan comedy or possibly satire. If you were a few clowns short of a circus you could actually believe zombies are real from reading this book.
The book covers what to do in different levels of a zombie outbreak ranging from just a few roaming zombies to a shambling horde of undead. It provides info on the best weapons and equipment to use in protecting yourself from a potential zombie attack and the best places to hole up if caught in the middle of said attack. It gives clear lists of crucial survival equipment you should have stored in case of a zombie outbreak and even provides an 'Outbreak Journal' for you to help catalogue actions leading up to an outbreak once you notice something suspicious.
Most importantly though the guide dispels the myths Hollywood has created around zombie attacks and how to deal with them. It highlights the ineffectiveness of flame-throwers, chainsaws and fragmentation grenades, it spells out the fallacy in using a boat as a refuge and it articulates why the most inhospitable places on earth are in fact the best places to be during a zombie attack.
All-in-all I found this to be a very amusing read. I did feel a little self-conscious about reading it on the bus where people might think of me as one of those crazy, survivalist, conspiracy theorists but having now read the book I can honestly say it was well worth the public humiliation.
