As her demanding career has left little time for friends or romance, her deepest relationship is with her mother, Vera March, a Russian immigrant and MS patient confined to a rehabilitation center. Vera is still haunted by the fact that her Ukrainian parents, innocent of any wrongdoing, were sent to the gulag, Stalin’s notorious network of labor camps, when she was just a baby.

Natalie would do anything to heal her mother’s psychic pain: it’s the one wound that she, a doctor, cannot mend.
