English settler Grace Ashwell flees an abusive lover in Hobart Town, with six-year-old Violet in tow. In her head, escape is easy: find work in the northern settlements and earn enough for passage home to London. But the terrain beyond the settled districts is wilder than Grace could ever have imagined. She and Violet find themselves lost in a beautiful but deadly land where rain thunders down mountains, the earth drops away without warning and night brings impenetrable darkness.
Deep in the wilderness, they find a crude hut inhabited by Alexander Dalton, an escaped convict long presumed dead. Hiding from civilisation in an attempt to forget his horrifying past, Alexander struggles to let Grace into his world.
