Query: An amazing novel, but not a masterpiece

Although very well written and thoroughly researched, this work is limited by the fact that Michelangelo's life, revoloving obsessively around marble, was otherwise uninteresting. Thus the focus turns towards historical events at the time and the novel often reads like a textbook. Stone must be praised, however, for the degree of historical accuracy captured in the novel and the vivid descriptions of Michelangelo's art.
