Natalie King is back: back from a stay on the psych ward. Her reluctance to live a quiet life has contributed to a severe depressive episode, and now it's time for a retreat to the country. A borrowed house on the Great Ocean Road; a low-key research job at a provincial university nearby. But Natalie and trouble have a strange mutual fascination. Her charismatic new boss Frank is friendly, even attractive. But it turns out his pregnant wife is an old enemy of Natalie's. And when Frank's tragic personal history is revealed—then reprised in the most shocking way—Natalie finds herself drawn deep into a mystery. And even deeper into danger.
