Cyber Storm by Matthew Mather.
From Amazon: CyberStorm depicts, in realistic and sometimes terrifying detail,
what a full scale cyber attack against present-day New York City might
look like from the perspective of one family trying to survive it.
It was OK. I guess I know too much about cyber, guns and survivalism to have enjoyed it more. I found the protagonist to be kind of weak.
Plus the guy that was the survivalist made so many rookie mistakes he had me shaking my head.
All and all it kept me interested.
--20th Century Fox has purchased the movie rights. I will go see it if it becomes a movie!
