The year is 1853, and the Habsburgs are Europe's most powerful ruling family. With his empire stretching from Austria to Russia, from Germany to Italy, Emperor Franz Joseph is young, rich, and ready to marry. Fifteen-year-old Elisabeth ("Sisi"), Duchess of Bavaria, travels to the Habsburg Court with her older sister, who is betrothed to the young emperor. But shortly after her arrival at court, Sisi finds herself in an unexpected dilemma: she has inadvertently fallen for and won the heart of her sister's groom. Franz Joseph reneges on his earlier proposal and declares his intention to marry Sisi instead. Thrust onto the throne of Europe's most treacherous imperial court, Sisi upsets political and familial loyalties in her quest to win, and keep, the love of her emperor, her people, and of the world.
