Married to Emperor Franz Joseph, Elisabeth -- fondly known as Sisi -- captures the hearts of her people as their "fairy queen," but beneath that dazzling perception lives a far more complex figure. In mid-nineteenth-century Vienna, the halls of the Hofburg Palace buzz not only with imperial waltzes and champagne but also with temptations, rivals, and cutthroat intrigue. Sisi grows restless, feeling stifled by strict protocols and a turbulent marriage. A free-spirited wanderer, she finds solace at her estate outside Budapest, where she enjoys visits from the striking Hungarian statesman Count Andrássy, the man with whom she's unwittingly fallen in love. But tragic news brings Sisi out of seclusion, forcing her to return to her capital and a world of gossip, envy, and sorrow where a dangerous fate lurks in the shadows. Through love affairs and loss, Sisi struggles against the conflicting desires to keep her family together or to flee amid the collapse of her suffocating marriage and the gathering tumult of the First World War. In an age of crumbling monarchies, Sisi fights to assert her right to the throne beside her husband, to win the love of her people and the world, and to save an empire. But in the end, can she save herself?
