I thought the book would be good, as I love history. But too many characters. They all blended into each other; I had to keep going over pagers to make sure who was who. Also the book repeats itself in some places, and the reader goes back to Charlemagne the person and Charlemagne the sub. I am a normal person who loves to read good books, to be taken to another realm of this world, away from everyday life. This book was too complicated in some parts. A good book should have twist and turns, but not too many that the characters blend into each other. Shame. This Basically as a good book for a long weekend, with nothing to do but read.
