When Kael, a quiet linguist in the city of Umuré, is called home to bury his grandmother, he discovers a hidden shrine beneath her house along with a mask he is warned never to wear. But after slipping it on during a trance, Kael becomes the unwilling host of Anoku, a long-banished deity of judgment.
Now, with divine power simmering beneath his skin, Kael becomes a target for cultists, monarchs, and spirit-walkers who either want to control him or destroy him. As he flees across sacred lands and forgotten shrines, Kael must reckon with the price of being a vessel for a god and whether he’ll lose himself in the process.
