Query: Disappointment to Say the Least

I ordered this book because I am a big fan of Turtledove's alternate history books. The story description was enough to get me interested and the story concept seemed pretty good. I can't believe that it was written by Turtledove. There was never any suspense on where the story was going or where it would end up, the characters were a little superficial. Though the story is not similar, for some reason I was reminded of "Farmer in the Sky" by Heinlein which I read a long time ago. The story was simple and pretty boring. It seems like this was written to become a series, and I am not sure I will buy any more if this series continues.
