A golden account of the reign of Charlemagne from the eyes of his son, Carl/Charles.
This book was read for school, and that, with the fact that this is set in an era formerly unread by myself, caused me to mentally yawn a bit at the beginning.
But then,....well, the real story got started. I was there! Sure, it took a bit to get into. The young characters are so mature and they "talk proper" and all that. All in all, I wouldn't wish to be a royal child; I can't take that much responsibility. And a lot of the time the Catholic Christian practices, though engaging, were plain weird; all that practically worshiping the pope was odd (Pease, take no offense if you are Catholic, but it is strange to moi.).
Although it doesn't cover everything, (I suggest looking Charlemagne and his family up in Wikipedia or such if you want to go into great detail) I highly recommend this book if you'd like to focus on the courts rather than the battles of this time.
In Son of Charlemagne, Willard masterfully paints a vivid representation of the sacrifices, the honors, and the bravery (not found exclusively on battlefields) it takes to be a king...and to be a king's son.
