One Second After by William R Forstchen is probably the scariest book you will ever read. It is in the military and and historical science fiction genre and deals with a topic that we can see reflected in today's headlines.

It is well written and researched and very nearly impossible to put down.

I highly recommend it, but warn you that it truly is scary as .... well you know.

Holy crap...I just read the premise of the book and some of the authors notes on his website. Scary stuff. EMP attacks are almost scarier than a nuclear attack and probably a more likely threat.

Better start survival training.
