This was an enjoyable zombie book. There's not much new here but the basics are solid.
It was interesting to have a female war vet cum small-town sheriff as the protagonist. The characters were well drawn and I'd like to find out more about them. I don't know if this is the first in a series or a stand alone novel. It works either way.
It's the first book I've seen that pointed out that the US government could freeze the Internet since so much of the backbone is here. Scary thought.
