The story of the relationship between the most devastating heavyweight boxer in history and the mentor who shaped him. When the legendary boxing trainer Cus D'Amato saw thirteen-year-old Mike Tyson fighting in the ring, he declared, 'This is the heavyweight champion of the world.' D'Amato played a crucial role during Tyson's formative years, legally adopting him at the age of sixteen and shaping him both physically and mentally after years of poverty. He trained the young boxer for several years, passing away a few months before Tyson became the youngest heavyweight champion in history. In the book 'Iron Ambition,' Tyson shares the life lessons that D'Amato imparted to him and reflects on how the trainer's wise words continue to resonate within him, in and out of the ring. The book timelessly highlights Cus's brave fight against the mobsters who controlled boxing, revealing more than we ever knew about this unique cultural character.
