I'm reading "Executive Orders" by Tom Clancy ...
The basic premise is what might happen if the whole US government is destroyed in an instant.
It was written in 1996 and starts out with a 747 crashing into the Capital and killing the president, all of Congress and the Supreme Court. (It's done by a Japanese pilot who has a personal vendetta carried over from Clancy's previous novel, "Debt of Honor".)
It's a pretty extreme thriller but something that I found particularly interesting was how Clancy used his characters to express his personal conservative political viewpoints. I found it refreshing to hear conservative views explained in a reasoned way, it's been so long since I've heard anything like that. I disagree with most of his conclusions but many of the points he made I would agree with. They were arguments that could open up discussions as opposed to today's conservative viewpoints that simply close out any further thought.
Boy things have changed.
