Omar El Akkad gets it right. A slight trend toward the World War Z style story but American War builds upon this idea with its own personal flair. A fictional future, a what if? A second Civil War fueled by division over the end of fossil fuels, quarantine zones and a biblical plague to top things off.
I love books like this because they reference modern trends and their certain destruction while writing matter-of-fact as if all of it has happened and been documented so completely.
You could say “If this happens, I don’t really want to live,” but inside the post-apocalypse are tiny traces of what makes us human, regardless of how bad things get. Get it, read it.
