Floyd Mayweather Jr's father was a boxer, as were his two uncles. His dad also dealt drugs and one day brought his work home with him, when he used his son as a human shield to stop a rival dealer from shooting him. The gunman instead shot his father in the leg, curtailing his own ring career. Floyd Mayweather Jr has never married, has four children by two women, and is a habitual gambler, known to win and lose millions on a single half of US football or basketball. He is obsessed with money, almost as obsessed as he is about protecting his unbeaten record and his staggering aim to go 50 professional bouts without defeat, a goal that he intends to achieve in late 2015, just shy of his 40th birthday. Tris Dixon explores his extraordinary life story in this searing, insightful and often brutal expose of one of the greatest athletes the world has ever seen.
