Cached UK/IE Kindle giveaway: 10 copies of Terry Pratchett's JINGO, a Discworld novel. This one is the one *most* about politics -- it involves two nation states going to war over R'lyeh. It has a hilarious use of Carrot, and is one of the few times in the entire series that Vetinari is caught completely by surprise.
As I usually say, pterry's books were educational. This one tries to teach us how to be critical about any call for fighting. And about cephalopods.
