For those in the early teens with a passion for history and a yen still for knights in armor and the romance of the Middle Ages, this tale is a thrilling one. The times are the times of Charles, later known as Charlemagne, progressive king of a European kingdom, great warrior, great statesman. And the central figure is young Sigmund of Fulda, a Frank, whose first contact with his king was as student in the palace school. Later he serves him in battle, using there the logic, the learning taught in the unheroic atmosphere of the schoolroom. The sights, the sounds, the dangers of life in those days, permeate the whole exciting story, woven into its rich fabric, tight action. The siege of a city, a spying mission, a true villain (the king's own son)- these are elements in a tale that makes history absorbing reading.
