In 2000 Norton published Morgan’s memoir, "Saturday's Child", in which she wrote candidly about "the shadowy circumstances of her birth; a lifelong, impassioned, love-hate relationship with her mother; her years as a famous child actor and her fight to escape show business to become a serious writer; her marriage to a fiery bisexual poet and how motherhood transformed her life; her years in the civil rights movement, the New Left, and counterculture; her emergence a leader of global feminism; and her love affairs with women as well as men," according to "BookNews.com". In her book, "her passion for writing, especially poetry, is vividly conveyed, as is her love and respect for her son, born in 1969," according to "The New York Times Book Review".
