This year's winner of the Booker Prize is British author Samantha Harvey for her fifth novel, Orbital. The Booker judges were unanimous in their decision. Orbital is set in the International Space Station and takes a bird's eye view of the earth as it orbits the world over a 24 hour period. The reader meets six astronauts and cosmonauts as they grapple with big questions of family, faith and grief, as well as mundane matters of domestic life in the space station. Samantha Harvey spoke to The Book Show's Sarah L'Estrange about her long running interest in space and how she wanted to write about it "as our one remaining wilderness".
