As daughters of the impoverished King of Montenegro, Militza and Stana must fulfill their duty to their father and leave their beloved home for St. Petersburg to be married into senior positions in the Romanov court. For their new alliances to the Russian nobility will help secure the future of the sisters’ native country. Immediately, Militza and Stana feel like outcasts as the aristocracy shuns them for their provincial ways and for dabbling in the occult. Undeterred, the sisters become resolved to make their mark by falling in with the lonely, depressed Tsarina Alexandra, who—as an Anglo-German—is also an outsider and is not fully accepted by members of the court. After numerous failed attempts to precipitate the birth of a son and heir, the Tsarina is desperate and decides to place her faith in the sisters’ expertise with black magic.
