A failed TV news reporter with a talent for shark-fishing returns to her hometown just as bodies begin washing ashore in this nail-biting suspense novel from the author of The Stranger Upstairs.

Minnow Greenwood, previously known for stealing her way into the hearts of viewers as Melbourne’s number one morning show host, is now back in her small hometown of Kangaroo Bay. After a horrifying and unexpected episode, she has no choice but to join her estranged brother in their family business of shark fishing. For an insomniac like Minnow, the work is strangely thrilling—there’s something alluring about the dark water at night. Something exciting, grimy… fitting. And maybe it’s not even so bad reconnecting with her brother, who’s the only person who ever saw her for herself. But the last thing she expects to surface on the beach is a human body.

Kangaroo Bay is a town quietly brimming with rage towards invasive tourists and host to a disquieting number of shark attacks—there’s no sympathy for the wayward swimmer. Except the media soon uncover that the victim was declared missing weeks before, and was long dead before they even entered the water. When the journalist in Minnow kicks back into drive, she discovers something for over forty years, there have been a steady number of missing persons around the area, including her own father’s disappearance ten years ago.

This is her one opportunity to reclaim her career as a journalist, and to learn what really happened to her father, but as Minnow digs deeper into the spate of missing tourists and the mystery of her father, she realizes someone is desperate to keep the secrets buried. . .and then another body washes ashore.
