My Darling Girl

McMahon follows up 2022’s The Children on the Hill with a chilling if predictable Christmas-themed supernatural mystery. Though Alison O’Conner dislikes Christmas, she’s the author of a successful holiday-themed children’s book, and her two daughters and chronically optimistic husband, Mark, adore Christmas with all the fervor of Hallmark movie characters. One afternoon, Alison receives a call from her alcoholic artist mother’s assistant, Paul, asking her to visit her mother, Mavis, in the hospital, where she’s entering the final stages of pancreatic cancer. Though Alison was abused both physically and emotionally by Mavis and still bears the scars, she agrees to see her, and eventually allows Mavis to spend the final weeks of her life at Alison’s Vermont home while Christmas approaches. As Alison sees her daughters and her husband begin to fall under Mavis’s spell, she comes to suspect the impossible—that the demonic woman who raised her may have been an actual demon all along. McMahon establishes a creepy atmosphere, but she gives the demonic shtick away early, and fails to provide many surprises or deepen the central metaphor from there. Still, readers who prefer their Christmas dinner with a side of supernatural dread may enjoy this. Agent: Daniel Lazar, Writers House. (Oct.)
