Orange Prize winner Kate Grenville talks to James Naughtie about her novel The Secret River and answers questions from a group of readers.

Told through the eyes of 19th-century deportee William Thornhill and his family as they arrive in Australia, the novel examines the themes of ownership, belonging and identity from the point of view of the settlers and the Aboriginal people who were already there.

Writing the book, says Kate Grenville, was 'like getting a new set of eyes and ears'.
