Query: Terrible compared to other volumes in the series

I love history books and have read just about all the books in this series.This one was very weak. It starts out okay, but as you go along, it just becomes what other reviewers have noted - a very opinionated, biased piece. But even more than that, the book stops reading as history and more as narrative mishmash of events with the ever present biased commentary.I hate putting books down once started but it took me the better part of two years to get to the end of this. I could only take a few pages at a time and then I'd have to set it aside for a while.Anyway, all I can say is this was a major disappointment.
