Describes Jack's descent into addiction and the low point he reached when his mum was diagnosed with cancer. This book tells the story of young man who has confronted his demons and defeated them.

Discovering a passion for extreme sports, he went from overweight and unfit to the lean young man he is today - courtesy of such adventures as running with the bulls in Pamplona, fighting a Thai martial arts expert known only as 'The Man' and scaling El Capitan, one of the world's toughest climbs. By turns funny, disarmingly honest and moving, "21 Years Gone" is the amazing story of young man who has confronted his demons and defeated them.
