'Hitlers War' by Harry Turtledove is his latest book and the first of a reported Trilogy. It just arrived today here, and I am anxious to start reading it. Turtledove has written several alternate history books - two about a Japanese Invasion of Hawaii, for instance - and this is his latest endeavor. The Synopsis: Neville Chamberlain does NOT sign the Munich Accord. What if Hitler had acted rashly, before his army was ready - would it have doomed him faster? Turtledove uses several view points (American Marines in China, the Abraham Lincoln Battalion in Spain, etc. I think it will be a good read like his other novels.

Love Turtledove! Thanks for the heads up. I read his 10 book series on an alternate WW1 and WW2 with the years in between also covered. They're worth a look if you haven't read them already.
I also got into these alternative histories a while ago. They give me the chills. It seems that people always think about the worse, Germany winning a war. But what about an alternative history where there is no Holocaust? Maybe the worst has happened...
