Book excerpt: Richard, last-born son of the Duke of York, was seven months short of his nineteenth birthday when he bloodied himself at the battles of Barnet and Tewkesbury, earning his legendary reputation as a battle commander and ending the Lancastrian line of succession. But Richard was far more than a warrior schooled in combat. He was also a devoted brother, an ardent suitor, a patron of the arts, an indulgent father, a generous friend. Above all, he was a man of fierce loyalties, great courage and firm principles, who was ill at ease among the intrigues of Edward's court.
