I just read that last week—in a couple of sittings, actually. It was in the SciFi section of the library, and I usually don’t read that genre, but it was highly recommended by others on FR, so I gave it a shot.
I thought it was funny because dh put in for a job transfer to Asheville :) The book, though, was definitely not funny and I had trouble sleeping Friday night!
I never really gave EMP much thought until reading that book. Eye opening, and scary as hell. The last third of the book was a little too Road Warrior like. I think a real event would more resemble post earthquake Haiti. But it did give it an exiting finish worthy of a movie.
