WILD DARK SHORE

The reality of climate change serves as the pervasive context for this terrific thriller set on a remote island between Australia and Antarctica.

Four family members and one stranger are trapped on an island with no means of communication—what could go wrong? The setup may sound like a mix of Agatha Christie and The Swiss Family Robinson, but Australian author McConaghy is not aiming for a cozy read. Shearwater Island—loosely based on Macquarie Island, a World Heritage Site—is a research station where scientists have been studying environmental change. For eight years, widowed Dominic Salt has been the island’s caretaker, raising his three children in a paradise of abundant wildlife. But Shearwater is receding under rising seas and will soon disappear. The researchers have recently departed by ship, and in seven weeks a second ship will pick up Dominic and his kids. Meanwhile, they are packing up the seed vault built by the United Nations in case the world eventually needs “to regrow from scratch the food supply that sustains us.” One day a woman, Rowan, washes ashore unconscious but alive after a storm destroys the small boat on which she was traveling. Why she’s come anywhere near Shearwater is a mystery to Dominic; why the family is alone there is a mystery to her. While Rowan slowly recovers, Dominic’s kids, especially 9-year-old Orly—who never knew his mother—become increasingly attached, and Rowan and Dominic fight their growing mutual attraction. But as dark secrets come to light—along with buried bodies—mutual suspicions also grow. The five characters’ internal narratives reveal private fears, guilts, and hopes, but their difficulty communicating, especially to those they love, puts everyone in peril. While McConaghy keeps readers guessing which suspicions are valid, which are paranoia, and who is culpable for doing what in the face of calamity, the most critical battle turns out to be personal despair versus perseverance. McConaghy writes about both nature and human frailty with eloquent generosity.

Readers won’t want to leave behind the imagined world of pain and beauty that McConaghy has conjured.
