Margery "Midge" MacPherson is at a ladies' boarding school with very little idea of what is happening on the front lines, and worried about her brother Tim, who lied about his age to join the army. When she receives news of his death, she believes it to be a mistake, and with two of her friends, she makes her way to Europe to find him. Midge is catapulted from her quiet boarding school life into the harsh reality of war-torn Europe, and the people she meets and the deeds she performs help to shape her world in a way she could never have imagined.
