When Marie Walewska hands Napoleon a bouquet of flowers on a frozen road, she sets in motion a passion that will reshape her life and echo through the halls of empire. Married at sixteen to an elderly count, she is asked by her country's greatest patriots to make an unthinkable sacrifice: win the Emperor's heart—and with it, Poland's freedom.What begins as duty becomes desire. From candlelit nights at Finckenstein Castle to the gilded chambers of Schönbrunn, Marie walks the treacherous line between love and politics, devotion and betrayal. She bears Napoleon a son he can never publicly claim, watches him marry another, and stands witness as the greatest army in history marches toward destruction in the Russian snow.
