Jane Harris, a stay-at-home mom in an exclusive California oceanfront community, is emerging from a year of mourning the accidental death of her older and favorite daughter, Mary, when she gets stunning news. A day before the memorial service for Mary and three days before the high-school graduation of her other daughter, Betsy, Jane learns that Mary, who was adopted as an infant from Elizabeth James, her in-laws' servant, was actually fathered by Jane's husband, David, during their first year of marriage. Then she gets evidence that David has bought a new house to share with his younger assistant, Kylie Dorn, with whom he's having an affair. And then she receives the first of several anonymous notes: MARY'S DEATH WAS NOT AN ACCIDENT. JUST ASK BETSY. In her first-person account, Jane is not a particularly likable character, and it becomes increasingly clear that she's also an unreliable narrator. Tension mounts as Jane makes plans for Kylie, Betsy, David, and Elizabeth, along the way dropping glimpses into her past, until the truth is uncovered. Involving psychological suspense that reveals the cracks in what seems a perfect life.--Michele Leber Copyright 2019 Booklist
