Granted, I didn't finish this book. However, I did enjoy what I read - the first half. Then it all just became too much of the same. The part I read was completely plausible (if Zombies happened to try to take over the world, I am almost certain that this book would be a great guide and will tell governments exactly what not to do and yet they will still handle it exactly like in this book).
But the actual zombies stop after about a third of the book and then the aftermath just continues, forever. I just have too much to read at the moment to finish it. But if the zombie apocalypse does happen, this will be my go to guide.
