This zombie survival guide really brings scientific evedince into the equation. Whether or not the evedince is true is up to you. All i can say is that if zombies were real this is what the book that would tell you exactly what they would be and how to survive it. Also it keeps religion almost completly out of it along with magic and voodo. It is worth the full buy and personaly i think it should be worth double the current price. Good job Max Brooks.
