I was hugely impressed with this alternative history, I had to keep reminding myself that this was actually fiction and not a real history. Very cleverly written.
I have read many alternative history novels and stories before and this really has to be one of the best ones. I have also read many of the authors previous books before and had mixed feelings about some of them but this is easily the best book he has written.
SPOILER ALERTS -
An interesting plot begins with the Heydrich surviving his Prague posting and working closely with German Intelligence, a new strategy with the German Navy completely destroying and stopping Allied Arctic Convoys supplying the USSR, Turkey coming in to the war on the German side, Manstein taking over strategy on the Stalingrad front with Paulus being transferred back to Germany all combine in to a plot where the Germans win the battle of Stalingrad and change the whole course of the war!
I wont say much more and leave you to discover the details of how the above happens and to discover the interesting conclusions but it really is a great read.
And the previous two reviewers are discussing the size of the book? Its a standard sized hardback novel with some pictures, photos and maps throughout.
