I liked it
I found it much more believable than UC or other similar themed books: that being corrupt and bullying govt agents doing whatever it takes to secure their jobs, a distant president who is completely unaware of the actual issues surrounding gun control who then reacts even more 'to the left' by issueing executive orders banning and restricting this and that, fanatically anti-gun politicians following suit, etc
More believable scenario, esp since i live in MD (not for long, though) and think that the reaction of the populace here to the 'stadium massacre' would be pretty much as it was described in EFD.
Very well done.
C-
p.s. and of course, another voice praising the choice of the author to leave out the gratuitous sex scenes that were present in UC.
