Wild dark shore

Australian writer McConaghy (Migrations) depicts in this urgent if uneven saga a family's attempt to survive on a desert island in a near future ravaged by climate change. After fleeing Australia eight years earlier due to fires, floods, and other natural disasters, Dominic Salt lives with his three children on Shearwater Island, a remote former research outpost between Tasmania and Antarctica, where he tends a seed vault meant to replenish global food supplies. His wife, Claire, died before the voyage, and he still has conversations with her in his mind. During a storm, his oldest daughter, 17-year-old Fen, rescues a woman named Rowan who washes ashore following a shipwreck. Radio contact with the outside world is impossible, as all the island's communication systems have been mysteriously destroyed, and it turns out that Rowan's missing husband, Hank, was the team leader of the island's research station. McConaghy ratchets up the tension as the characters' paranoia and mutual suspicion increases and their motives are revealed, though she scuttles the momentum with predictable romantic subplots, and a late-stage plot twist strains credulity. For the most part, though, McConaghy blends entertainment with a sobering message about conservation and the impacts of geographic isolation. Readers of climate fiction ought to check this out.

Sub-Antarctic noir meets a love letter to the rapidly disappearing wild world in McConaghy's latest (following Once There Were Wolves). Dominic Salt and his three children are caretakers of a remote island near Antarctica, home to the Shearwater research base and the world's largest seed bank. Rising seas have been threatening the island, and readers meet the Salts as they are considering evacuating the island with their precious seeds. When a woman named Rowan washes up on shore, the Salts take her in and nurse her back to health. As Rowan recovers, she gets to know the family: Raff, Dominic's oldest son, is doing his best to channel his grief and rage from tragic heartbreak; Fen, his 17-year-old sister, is such a water creature that she lives among the seals; and Orly, the youngest boy, is consumed with love for the natural world. Rowan shares pieces of her past with the Salts, but unraveling the island's mysteries brings them both closer to hidden truths. As the seas rise to swallow the island, a race against time tests each person's love and loyalty. VERDICT As lush as it is taut with tension, this novel is filled with both the joys and ravages of nature.--Julie Kane
