that and act on it while the husband refuses to. The Idea of Perfection is about people haunted by the impossible ideal of perfection. The two main characters are both middle-aged and frumpish, and consider themselves unlovably flawed. The journey they make is to recognise that to be "imperfect" is simply to be human, and carries its own power. As the epigraph from Leonardo da Vinci asserts: "An arch is two weaknesses that together make a strength". The Secret River is set in early 19th-century Australia and is based on the story of one of Grenville's convict ancestors, Solomon Wiseman, a London boatman transported for theft.

It's a story about secrets and lies, and how to deal with a dark legacy from the past. Grenville has said that the book is set in the 19th century, but is as much about the ugly secrets in Australian history that her
