SHADOW BOX is one of George Plimpton's most engaging looks at professional sport through the eyes of an amateur. Stepping into the ring against the light-heavyweight champion Archie Moore, Plimpton pauses to wonder why he ever became a participatory journalist. Bloodied but unbowed, he holds his own in the bout - and brings back this timeless look at boxing and its devotees, among them Muhammed Ali, Joe Frazier, Ernest Hemingway, and Norman Mailer.
