Book excerpt: Muhammad Ali is the greatest boxer the world has ever known and the most charismatic athlete of all time. Adored by millions, Ali is a role model and symbol of courage to us all. Davis Miller was a small, sickly child mourning the loss of his mother when he first encountered Ali. From this meeting, there developed a strong personal relationship that has lasted more than thirty years. Brilliantly weaving Ali's story with his own coming-of-age memoir, Miller captures the true meaning of hero worship, fathers and sons, and strength through wisdom.
