alternative history

Philip K. Dick, a science-fiction writer known for his originality (among other things, he wrote the story, entitled "Do Androids Dream of Electric Sheep," upon which the movie Blade Runner was based) has a very interesting book that uses as its basic premise that the Axis powers triumphed in World War II. It takes place in the US, but a US dominated by Japanese culture and Nazi ideology - it's called "The Man in the High Castle," if memory serves.
