Usain Bolt's agent says representatives for the record-breaking track star are in talks with publishers about a biography. Ricky Simms says he's negotiating a deal for a book for the sprinter but can't discuss many details yet. As for the scope of the book or how much of Bolt's off-track life might be included, Simms says all of those aspects are being negotiated. Bolt emerged as a superstar at last year's Beijing Olympics, winning gold medals in world-record time in the 100 meters, 200 meters and 4x100-meter relay. He took home golds in all three events again at this month's world championships – smashing his own records in the 100 and 200.
