Steve Redgrave is an amazing rower. We get to learn something about the cost of his unparalleled Olympic achievements. But this is not a dramatic book, rather a somewhat rambling memoir, transcribed by Redgrave's cowriter.
If you're a huge Redgrave fan, rowing fanatic, or Olympic sport freak, get it. If you want to learn how to row, buy Redgrave's Complete Book of Rowing (or better yet, Frank Cunningham's Sculler at Ease, which covers sweeps too). If you want Olympic drama, buy The Amateurs by Halberstam or Assault on Lake Casitas by Brad Lewis.
