Kaden, the heir apparent, was for eight years sequestered in a remote mountain monastery, where he learned the inscrutable discipline of monks devoted to the Blank God. Their rituals hold the key to an ancient power which Kaden must master before it’s too late. When an imperial delegation arrives to usher him back to the capital for his coronation, he has learned just enough to realize that they are not what they seem—and enough, perhaps, to successfully fight back.

Meanwhile, in the capital, his sister Adare, master politician and Minister of Finance, struggles against the religious conspiracy that seems to be responsible for the emperor’s murder. Amid murky politics, she’s determined to have justice—but she may be condemning the wrong man.
