The crown's game
(Book)

Vika Andreyeva can summon the snow and turn ash into gold. Nikolai Karimov can see through walls and conjure bridges out of thin air. They are the only enchanters in Russia, and when the Ottoman Empire and the Kazakhs threaten to attack, the tsar wants a powerful enchanter by his side, and as an advisor for the prince, Pasha. He initiates the Crown's Game, a duel of magical skill, and the winner will become his Imperial Enchanter; the loser will die. For Vika and Nikolai, the game is a chance of a lifetime, but they come to realize that their growing regard for each other makes the game impossible to win. And as long-buried secrets emerge, threatening the future of the empire, it becomes increasingly clear to them that the Crown's Game is not one to lose.
