I have enjoyed every book in this series (well... accept maybe the first) and perhaps this one most of all. Turtledove's writing has gotten better with each book he publishes and the story it's self is just at a really exciting point. I was left both wanting to jump into and through the next two volumes yet maybe wanting to take them slow being I know the series is over then.
The tipping point of the war comes pretty suddenly in this, and you do start to get this clear picture of a smaller country taking on too much against a bigger one. And although it is horrifying and awful to contemplate as a real event the black holocaust section of the book was something that always kept my attention. Towards the end of the book I found myself on the edge wondering how much longer this can last, wondering it the U.S. will find it and what will happen. Above all it has me interested in reading up on the real Holocaust, especially what happened at the end of the war as the Allies were discovering it. I feel like that's when alternative history is at it's best, when you put it down and want to know more about real history.
