I read halfway through this book at one sitting, then gave up. The book was exciting but very frustrating. Every single figure in a position of authority is shown as being evil or stupid. Unfortunately, that includes the main character, a teacher who is clearly too lucky to die and too stupid to live. He keeps making mistakes which, in context, should be thoroughly fatal. He also murders two policemen early in the story. Crooked cops who were in no way a danger to him, but they were evil enough to die, for cheating people on phony traffic tickets during an emergency. Um, what? That whole scene didn't even make sense, and neither did the escape that followed. Everything has fallen apart, except the power lines leading to gasoline pumps? Homeland Security opening fire on survivors who are somehow "competing" with them? And the central character survives the crossfire?
Okay, so let's ignore that as being survival by writer fiat. Several times.
I was willing to forgive a few such cases, but they began to add up. That, combined with the mindless evil of the police, FEMA, Homeland Security and every government official at every level, just wore me down. The author's ongoing anti-government random diatribes wore thin when he was openly critical of FEMA being able to make all-channel emergency radio broadcasts, but I was still curious about the story at that point, so I kept reading a while longer.
Crooked cops extorting a few dollars while civilization collapses...okay, I can see that happening, maybe. U.S. Army troops firing on each other out of what appeared to be boredom, after all the officers just sort of wandered off [where did they GO, in the middle of a zombie siege?], that was way too much. It broke the shock absorbers on the suspension of my disbelief.
The basic premise of the book seems to be, if people start getting infected with a serious plague and the government orders everyone to stay put, the proper thing to do is to scatter in all directions. There is a flaw in the supposed logic of this. Let's replace "zombies" with any other serious plague with a semi-known transmission method. If you have no way of knowing if you're a passive carrier of said plague, there's a good chance you've just killed a whole bunch of people. In this story, since the zombie plague begins with what appear to be spontaneous outbreaks, this is exactly the scenario. The zombie plague is being spread by direct contact AND something else. So, how do you know you're not spreading it yourself? You don't, and you've just helped the world to die. The end.
I only gave this book a second star because the author really can write good fight scenes. They are the high point of the story.
