The most impressive part for me however was not Jack stellar job at describing zombies that eat their own brains, or the way he can twist a story so much you aren't even sure you can trust yourself, or even how he has the genius to create an "outside" perspective through radio show called (straight-forward enough) "Zombie Radio." Nope...Jack's most impressive feat in this entire book was his ability to keep the technology talk from sounding like a "Hacking For Dummies" learners manual. With Bethany's main duty being "hacking" this whole angle could have very easily come back to bite Jack in the ass. Instead, he chose to give just enough info to sound convincing (and knowledgable) without making me drool on my kindle.
