The baby, whom she had named Barbara, had been given up for adoption.Years later, when Campbell had remarried, one of his sons received a call from Eileen: she had cancer and was dying. At the same time, a forty-year-old woman was trying to trace her mother. Finally she tracked down her uncle: she was Barbara, she told him, and Eileen was her mother. The uncle feared that Eileen was too sick to cope with the news, but Barbara then revealed an awful fact: she too, had cancer and time was short.All That Really Matters is the remarkable story of two extraordinary women who had to live a whole lifetime of caring in a few short weeks.
