The Family Next Door by Sally Hepworth

In a suburb of Melbourne, the reader gets to know three families who live on Pleasant Court. There's Essie, who lives with her husband, Ben and her two young daughters. Essie left her older daughter, Mia, at a park when she was a baby, and seems to be dealing with postpartum depression after the birth of her second child, Polly. Real estate agent, Ange, is married to Lucas, with two boys, and has concerns about her husband's fidelity. Resident Fran, like Essie, has two little daughters and is married to Nigel. She is harboring her own secret and struggles with keeping it hidden. When new neighbor Isabelle moves onto Pleasant Court, it becomes clear that she has moved to the street because she believes someone has kept something hidden that involves her. Will anyone's lives ever be the same? A great read-alike for readers of Liane Moriarty.
