Well, I read the book right after "LZR-1143" Volume 3 Bryan James is a concentrated action with humor that goes a hundred miles an hour.

There, nothing to see.
It is limited in the area of camera, with an average city and its periphery secured by high walls; it made me immediately brings to mind "The Walking Dead" with the city of Woodbury but significantly larger.
The dominated and dominant while outside the zombies do an Office of decor.
This would lead almost to the complaint.
However, the story remains consistent and interesting allowing to read the book without too depressed about the lack of zombies ...
