Query: Once again, Turtledove has hit the mark

With an eye toward history and another on fantasy Turtledove has allowed us to walk in the Empire once again. His Time of Troubles series has continued his fictional history of the Big V, and I am struck at the lack of "common" plot themes. The heroes are enemies, the victory is won by chance and cunning, and the story takes the reader far past the typical end point of "we win." Well done, and keep them coming! I am wondering just WHO will rise on the Shield as the next Avtokrator........
