I will say that the author is a skilled writer from a mechanics standpoint, but the plot was full of holes. Sure, some originality in this genre is a good thing, but departing from the well-trodden science of EMP effects sometimes begs some explanation, especially considering the main character is a scientist of sorts.
The protagonist is an angst-ridden juvenile - oops, scratch that, an angst-ridden narcissistic twenty-something who acts like a juvenile, and who despises mainstream American values. The antagonist is a famous close-minded cowardly preacher/evangelist with thousands of jihadi-like followers throughout middle America (yup, that again). Also, this antagonist seems to have an unexplained magical power of communication throughout the country with his brain-dead acolytes in a post-apocalyptic America where even batteries are fried and magnets no longer attract.
I must be honest, I was unable to read more than halfway through the book - it was simply too filled with elitist stereotypes and unexplained far-fetched "science". The kicker for me was the the "Go To" location to wait out the end of the world was Chicago because of its "plentiful fresh water and moderate climate." Really?
I did give this one star book a second star because the author does have skill, but I believe he needs to look into changing to a genre where he may find more readers who are more in tune with his outlook.
