I recently finished The Man in the High Castle, which I really enjoyed. What are some other decent titles in the same vein of alternate military/political history?
Harry Turtledove's Southern Victory series.
Guns of the South by Harry Turtledove.
While it's nowhere near the level of Dick's writing, it is enjoyable and feels authentic.
Guns of the South is a "what if" book about Neo-Nazis going back in time to give AK-47s to General Lee's army, and the subsequent victory over the north.
It's fun. The cover has Lee holding an AK-47. What more could you want?
