Roddy speaks about why writing difficult conversations is so satisfying as a novelist. Australian rom-com author Nina Kenwood takes The Book Show to her childhood home in the Victorian seaside village of Queenscliffe where her love of reading and writing was fostered. Nina explains why the main character in her latest novel, The Wedding Forecast is also a writer and how Nina focuses as much on getting the comedy right as the romance in her fiction. Michelle de Kretser is a two-time winner of the Miles Franklin literary award and is one of our country's most celebrated authors. Lately, Michelle has been set on redefining what exactly a novel can be. Theory and Practice is advertised as a novel but its narrator bears a strong resemblance to the author. Is it a novel, a memoir or something else altogether?
