Anna is the central character in The Good Mother. Recently divorced from her husband Brian, Anna works as a private piano teacher and, later, as a research technician working with rats in a laboratory at Boston University. Anna is self-reflective and sensitive, but she lacks a clear identity and a strong sense of self, having grown up burdened with her family's expectations for her professional success. Anna is mother to four-year-old Molly, and after the divorce she takes on full custody of her daughter.
