Iris, a young Australian nurse, travels to France during World War I to bring home her fifteen-year-old brother, who ran away to enlist. But in Paris she meets the charismatic Dr. Frances Ivens, who convinces Iris to help establish a field hospital in the old abbey at Royaumont, staffed entirely by women-a decision that will change her life. Seamlessly interwoven is the story of Grace, Iris's granddaughter in 1970s Australia. Together their narratives paint a portrait of the changing role of women in medicine and the powerful legacy of love.
