Reddit mentions of Domestic Enemies: The Reconquista

You certainly have a good start. There are a few things in your list that are still in my to read pile. I see a few holes in your collection that I am sure that you will eventually get to reading:

• Lights Out by David Crawford
  
• Enemies Foreign And Domestic by Matthew Bracken
  
• Domestic Enemies: The Reconquista by Matthew Bracken
  
• Foreign Enemies And Traitors by Matthew Bracken
  
• Alas, Babylon by Pat Frank
  
• Lucifer's Hammer by Larry Niven and Jerry Pournelle
  
• Apocalypse Law by John Grit (first book of a series)
  
  Personally, I prefer Joe Nobody over A. American. Glen Tate's series is good but runs out of steam towards the end. John Grit's first book is rough but the series gets better. I couldn't get past Bradley's first book. I am sure I could list more books but my bookcases aren't very organized at the moment.
  
  I would also highly recommend that you branch out into dystopias. There is a lot of shared space with apocalyptic fiction. There is a lot to be learned from 1984, Brave New World, It Can't Happen Here, Wool (series) and The Iron Heel.
