An epic wartime tale in which a young woman faces hardship, danger and impossible choices as the events of history sweep her across continents, and two suitors compete to win her heart.Sixteen-year-old Marta has always longed to follow her father and lead armies into battle. Instead she finds herself leading her fellow girl-guides on a camping trip on the border between Poland and Germany on the very day in September 1939 that the Nazis invade. Immediately the girls are spirited across their Polish motherland to take refuge in a remote nunnery, but their safety is soon under threat . . . So begins a perilous adventure across thousands of miles - from the logging camps of frozen Siberia to the British field hospitals of Persia - during which Marta is forced to draw on reserves of courage she didn't think she had and make choices she never imagined she'd face, as her heart is torn between a young Polish patriot and a charismatic Iranian doctor.
