"A bit dry but OK"
This book takes a bit of work to listen to. The reader has an English accent, an echo is added to the quotes, and there is medieval filler music between chapters. The effect is a bit like watching a filmstrip or movie in high school, between the production style and the stories of unfamiliar people like Pepin, Charles Martel, and the like. This does make it educational, however and overall the book is pretty good. Being the biography of an emperor it emphasizes political history more than social. I'm finding that I like social history better, but there were enough nuggets of information on regular life that the book was good for me. Specifically, I always wondered why you couldn't just live on your piece of land and be left alone. Now I know.
If you are interested in Charlemagne and the history of his time, the book is worthwhile but plan on working some to get through it.
