Query: Not believeable

I found the characters including the historical ones to be unbelieveable. I don't think some of the historical figures would have acted as they did. The aliens are naive beyond belief. They just don't seem that bright. I don't think they could successfully invade my grandmother's kitchen. The aliens can somehow cross lightyears of space, but their technology doesn't seem to be more advanced then that shown in the Gulf War. A worthy attempt at an alternative history that just falls flat. I don't think I'll bother finishing this series. Try Harry Harrison's East of Eden for a great alternative history.
