Yet another clueless attempt at an "end of the world" story.
Within the first chapter, disaster strikes.
Literally within seconds of the EMP, (that no one knows about) everything has erupted into chaos, everyone has panicked and is running around madly, fighting, looting etc. Within minutes citizens are robbing, murdering, kidnapping, raping anyone who passes by.
And the author clearly has no clue, and gas done no research about guns or even the basic functions and designs.
If you are clueless too, you'll likely find this to be "awesome".
If you have even basic knowledge of firearms, human tendencies in response to disaster and tragedy etc, then you'll very likely find this to be unreadable.
