Sarah is the youngest child of William Thornhill, an uneducated ex-convict from London who has built his fortune on the blood of Aboriginal people. With a fine stone house and plenty of money, Thornhill has re-invented himself. As he tells his daughter, he "never looks back," and Sarah grows up learning not to ask about the past. Instead her eyes are on handsome Jack Langland, whom she's loved since she was a child. Their romance seems destined, but the ugly secret in Sarah's family is poised to ambush them both.
