Book excerpt: On a hot July night on Cape Cod, at the age of 14, Brodeur became a confidante to her mother's affair with her husband's closest friend. Malabar came to rely on her daughter to help, but when the affair had calamitous consequences for everyone involved, Brodeau was driven into a precarious marriage of her own, and then into a deep depression. In her memoir she examines how the people close to us can break our hearts simply because they have access to them, and the lies we tell in order to justify the choices we make. -- adapted from jacket
