You need to read this. Yes, You.
One Second After
This book is fiction. The danger of an EMP strike is not. Of all the things our country is worried about, this will have you calling your Senator and Representative and asking them why they aren't working on hardening our systems for this possibility. One nuclear warhead, detonated above the atmosphere over the continental United States would wreak havoc on our entire society. And the technology is not beyond the likes of small countries who already hate us.
So get your favorite blanket and be prepared to read a book you can't put down even though the part of you that would like to not know this will want to with every turn of the page.
