The Man with the Iron Heart by Harry Turtledove. I wanted to like this book more, as I I have read a lot of his other works and enjoyed them a lot. Really, I did. But unlike a lot of Turledove's books this one felt really heavy handed in the manner in which he overlaid post WW2 Germanywith contemporary events.
With the non-death of Reinhard Heydrich the Allies encounters a true opposition in post-defeat Germany. Heydrich has had 3 years to prepare for the downfall and subsequent resistance inside Germany. And to anyone who has followed the news in the past decade, every tool that Al Quada has deployed is in the arsenal of Heydrich's Werewolves. Suicide truck bombs, suicide bombers, IED's, other traps and even the kidnapping and execution of service members (caught on camera of course).
Maybe this book works for other people but I personally am exhausted from our own War against Terror that uses the same tactics, reading about them set into 1945-48 just felt like a chore.
