Set to spy on her, Vavara soon becomes her friend and confidante, and helps her navigate the illicit liaisons and the treacherous shifting allegiances of the court. But Sophie's destiny is to become the notorious Catherine the Great. Are her ambitions more lofty and far-reaching than anyone suspected, and will she stop at nothing to achieve absolute power?
