Sonia O'Sullivan is one of the greatest sporting figures Ireland has ever produced. In a career which saw her competing at the highest international levels for over a decade, she turned in world-class times in events ranging from the 1,500 metres to the marathon, capped by World Championship gold in the 5,000 metres in 1995 and Olympic silver in the same event in 2000. But her performances on the track are only part of the story of this passionate, sometimes fragile, and always compelling athlete. Now, Sonia tells the full story of her life for the first time - from her childhood in Cobh, County Cork, through her early successes on the track, to the highs of 1995 and 2000 and the low of the 1996 Olympics. Whether in triumph or in tears, Sonia has always been a uniquely fascinating - and mysterious - figure. This frank autobiography takes us behind the scenes of international athletics and behind the mask of a brilliant, vulnerable sportswoman.
