SONG OF THE MOCKINGBIRD is the story of a mature woman's self-discovery. Five years widowed but still bound to the man to whom she was married for thirty years, Doris gradually comes to discover her life not only is not over but is just beginning in ways she had never imagined possible. In the process, she also discovers a good deal about her marriage that contradicts the ideal image of it she has nurtured all her adult life.

Meanwhile, her daughter's own marriage is breaking up. After her father's death Evelyn willingly took over his role as her mother's guardian. Strong-willed by nature, she is nevertheless at a loss when she is no longer able to control her husband's will. Alone with a small child, she comes to discover that the mother she has treated almost as a second child is a source of strength where she had least expected one.

Doris's odyssey includes close friendships with two women who despise each other, a love affair which awakens her to a sense of her own sexuality she had never thought possible, and a new relationship with the daughter she has previously seen as merely a female clone of her late husband.
