This biography about Muhammad Ali is a high-interest, low-vocabulary book for adolescents and adults with limited literacy skills. Born Cassius Clay, Ali (1942- ) brought unprecedented speed and grace to the sport of boxing. The phrase "floats like a butterfly and stings like a bee" comes to mind when we think of Ali. Sports Illustrated named him "Sportsman of the Century." In 2005, Ali received the United States of America's highest civil award, the Presidential Medal of Freedom. Ali not only became one of boxing's greatest but throughout his career also remained a person of principle.
