There was plenty of action, and the characters were all very believable, as they represented a realistic cross-section of the RKBA community.
It portrays what would likely be the response to any treason against the Constitution that is committed by tyrant-wannabees. Instead of large scale 'milita groups' taking action, it would most likely be individuals or small groups of individuals. "Friends helping friends" as one of the characters said.
The ending took a couple of interesting twists, but still turned out pretty well.
All in all, it was fun to read and one of the few books I've had a hard time putting down. Thanks for writing it, and for your support of the Constitution.
