From the bestselling author of The Prince of Providence comes a revelatory biography of Rocky Marciano, the greatest heavyweight champion of all time.

The son of poor Italian immigrants, with short arms and stubby legs, Rocky Marciano accomplished a feat that eluded legendary heavyweight champions like Joe Louis, Jack Dempsey, Muhammad Ali, and Mike Tyson: he never lost a professional fight. His record was a perfect 49-0.

Unbeaten is the story of this remarkable champion who overcame injury, doubt, and the schemes of corrupt promoters to win the title in a bloody and epic battle with Jersey Joe Walcott in 1952. Rocky packed a devastating punch with an innocent nickname, "Suzie Q," against which there was no defense. As the champ, he came to know presidents and movie stars-and the organized crime figures who dominated the sport, much to his growing disgust. He may have "stood out in boxing like a rose in a garbage dump," as one sportswriter said, but he also fought his own private demons.

In the hands of prizewinning journalist and biographer Mike Stanton, Unbeaten is more than just a boxing story. It's a classic American tale of immigrant dreams, exceptional talent wedded to exceptional ambitions, compromises in the service of a greater good, astounding success, disillusionment, and a quest to discover what it all meant. Like Suzie Q, it will knock you off your feet.
