As it is Sunday, we shall now switch out On Stranger Tides for Harry Turtledove’s Liberating Atlantis. It’s the third book of an alternate history series where the eastern half of the North American continent (named Atlantis by the inhabitants) had apparently been detached millions of years previously and more or less parked in the middle of the Atlantic Ocean. The previous two books highlighted the alternate’s version of the Age of Discovery and the American Revolution; this one looks to address Atlantis’ version of the American Civil War.
Or you could just buy it because it’s by Harry Turtledove. I find that to be a remarkably successful book-buying strategy.
