I enjoyed Volume 1 (Books 1-3) and half of Volume 2 (Book 4 and some of 5) very much, but then it went off the rails. Prior to book 5, it was what I considered “Apocalyptic Light”. Yes, the land was lawless, but there was enough infrastructure around somehow to have a never-ending supply of guns, bullets, bombs, etc. All great fun, and the characters were interesting and mostly apolitical. The reason for the collapse of American civilization is never fully explained, but that didn’t really matter to the ongoing storyline.

But then in the middle of Book 5 the author decided the real villains were the United Nations (!) and peacekeeping troops. What!?! The “good guys” were elements in the remaining US government who could now go about killing all the perceived enemies of the US without worrying about any sort of due process or procedures. I’m not sure what got into the author, but it went askew very quickly in book 5.
