Great book series . Location set mostly in the Sevier Co. – Wears Valley area with Blount and Knox counties included . Very descriptive about the settings in book 4 , i think it was . Ryan either did his homework really well or has visited extensively since it is an awesome vacation spot . Book series of almost 60 hours was a main draw , but the post-apocalyptic survival theme is an intresting genra that is either done well like this series was or it includes super survivor preppers that can’t be killed . This was the first series by Ryan Schow and i well be listening to more of his books . Awesome writer .
