The first portion of the book, dealing with serfs, was truly fascinating to me and I enjoyed learning and then understanding the traditional / old school view of feudal society, the more modern view that the author is critiquing (quite passionately), and the author's position on how we should really be interpreting events in France around the year 1000. I especially appreciated getting a more nuanced look at what serfdom really meant to people of the time - high school history left me with a very simplistic view (serf = poor folks, bottom of feudal society) and I loved that he analyzes legal contracts of the time to give a more in-depth, colorful (possibly controversial) understanding of serfdom. The sections on knights and on the understanding of events around the year 1000 were also interesting, if less riveting to me personally.
However, I am not an academic and this book was most certainly not meant for easy reading outside of academia! It was a tough, tough slog to get through. It's taken me three attempts over 7+ years to actually complete the book! So although I suspect I'd give the book four or five stars if I was a medieval historian, I'd give it three stars for the curious but non-academic reader. Perhaps an apology is owed for the low rating - The fault, dear reader, is not in our stars but in ourselves...
