Is Annie's new acquaintance a needed confidante or a threat? A dark prologue from a file on Annie Lin's laptop describes her life as one long nightmare, mentions a plan involving the safety of her son, and alludes to her own disappearance. All this is in stark contrast to the hopeful and often sunny narrative that follows. Annie has moved to beautiful Kauai with her young son, Finn, determined to start a positive new life. Not even Kalani, her intrusive neighbor, can dampen her enthusiasm. She even gets to play good Samaritan by helping stranded motorist Serena with wine and temporary refuge. Before long, Annie's sharing confidences with Serena as if she were an old friend. Suspense arrives courtesy of an increasingly menacing storm, the threading through of more bits from the laptop file, and selections from an ongoing text thread between Annie and her sister Sam, who's helping her forge that new life following her separation from husband Brody. Readers will be well ahead of Annie in perceiving that Serena is not what she seems. Butler's third novel is packed with familiar thriller tropes, like the way Annie's dog, Marley, growls at Serena when they first encounter her. For the most part, though, the author folds these in expertly and seamlessly, grounding her tale in the themes of complex family relationships and racial identity she explored in The Tiger Mom's Tale (2021). Readers can decide whether the reveal and what comes after live up to the foreshadowing. A skillful by-the-numbers thriller with its share of nice touches.

Annie Lin, the protagonist of this unsettling thriller from Butler (The Red Thread of Fate), has recently moved from New York to Kauai, Hawaii, with her husband, Brody, and their four-year-old son, Finn. She hopes the change of scene will provide comfort and stability for Finn, who suffered a traumatic accident six months earlier, and shore up her shaky marriage. But most of all, Annie hopes to regain some semblance of normalcy after personal and professional failures, including the bankruptcy of her dance studio, have left her depressed, resentful, and difficult to be around. She's even started to doubt her own sanity. As the family adjusts to a fragile happiness, severe weather rocks the island, and a strange woman appears at their door seeking shelter. What happens next forces Annie to question everything in her life as she wonders whether this stranger is friend or foe. Well-developed characters and plenty of local color add to the slowly simmering plot, which builds to a strong and unexpected climax. Alfred Hitchcock fans will be satisfied.
