My latest read is an alternate history story, Fortitude by Andy Duncan. The story was nominated for a Nebula in 2000. It tells the story of George S. Patton's career, as if he knew he had lived it before. I have heard he really thought this, but couldn't find confirmation. The story itself is well told, but it mostly sticks to events, with a lot of time inside Patton's head. And I didn't really find him compelling. 2 stars.
Harry Turtledove and David Drake do this sort of thing well. Harry Turtledove has a new set of stories, Hitler's War, out this year.
