Vika Andreyeva, with her power to summon snow and transform ash into gold, and Nikolai Karimov, who can see through walls and create bridges, are the only enchanters in Russia. As threats from the Ottoman Empire and Kazakhs loom, the tsar initiates the Crown's Game, a magical duel where the winner becomes the Imperial Enchanter and the loser faces death. Raised on a small island, Vika is excited to showcase her talents in Saint Petersburg, but can she defeat Nikolai, whose magic captivates her?

When the tsar's heir, Pasha, also falls for Vika, Nikolai must either defeat her or risk his own life. As hidden secrets surface, threatening the empire's future, it becomes clear that the Crown's Game is a battle neither enchanter can afford to lose.
