She Came Back As The Housekeeper

Grace Foster survives the crash, but not as herself. Her face is marked and her voice is gone, and nobody can confirm who she is. So she takes work inside her own family under a different name, as a housekeeper who does not speak, and watches her son Leon from across the room, guarding him without ever saying who she is. What she finds there is a wife plotting to take the family fortune, and she is not plotting alone.
