Sarah Thornhill is the youngest child of William Thornhill, convict-turned-landowner on the Hawkesbury River. She grows up in the fine house her father is so proud of, a strong-willed young woman who's certain where her future lies. She's known Jack Langland since she was a child, and always loved him. But the past is waiting in ambush with its dark legacy. There's a secret in Sarah's family, a piece of the past kept hidden from the world and from her. A secret Jack can't live with. A secret that changes everything, for both of them. Kate Grenville takes us back to the early Australia of The Secret River and the Thornhill family. This is Sarah's story. It's a story of tangled secrets, a story of loss and unlooked-for happiness, and a story about the silent spaces of the past.
