Oscar and Lucinda by Peter Carey
It tells the story of Oscar Hopkins, the Cornish son of a Plymouth Brethren minister who becomes an Anglican priest, and Lucinda Leplastrier, a young Australian heiress who buys a glass factory. They meet on the boat over to Australia, and discover that they are both obsessive gamblers. Lucinda bets Oscar that he cannot transport a glass church from Sydney to a remote settlement at Bellingen, some 400 km up the New South Wales coast. This bet changes both their lives forever.
