Kirsty Young's castaway this week is the author Peter Carey. He says he grew up in his homeland "thinking that Australian history was dull and Australian literature was dull" and that he developed a strong passion to make it new and fresh. In this he has surely succeeded - he is one of only two novelists to have been awarded the Booker Prize twice.

Yet he came to writing relatively late. The son of a car salesman he started off studying science but he abandoned his university career and ended up, in his 20s, drifting into advertising. It was only then that his literary awakening began. "I announced with great confidence one day, 'I’m going to be a writer',' he says, 'I’m an obsessive fool, I was determined to do it!"
