Rui is an Exorcist-in-training with one goal in mind - honing her magic to avenge her mother's death. Yiran is the black sheep of an illustrious family. The world would be at his feet - had he been born with magic. But when an accident causes Rui's power to transfer to Yiran, everything turns upside down.
Without her magic, Rui has no tool for vengeance. With it, Yiran finally feels like he belongs. As dangerous monsters overrun the city, Rui will do whatever it takes to regain her power. Even if that means making a deal with a shadowy stranger to track down a god who does not wish to be found . . .
