John Irving is the author of The World According To Garp, A Prayer for Owen Meany, The Cider House Rules and many other works of fiction. His latest novel is called In One Person.
We've invited Irving to play a game called "The World According to Gorp." Garp is about sex, castration and bears. Gorp, on the other hand, is the mix of "good old raisins and peanuts" you eat when you're hiking.
