Emi has dedicated her life to becoming the perfect vessel for the goddess Amaterasu, but the insidious betrayal of another deity has changed everything. Now Amaterasu has charged Emi with an urgent mission: to find and free the earthly gods before mankind is brought to its knees beneath divine tyranny.

At her side is Shiro, the mysterious fox spirit. When she first saved his life, she could never have imagined that behind his cunning and confidence, he was lost-his power bound by a devastating curse and his memories obscured. His veiled history is somehow tied to the missing gods, but he can't remember how or why.

As their search leads them into the murky depths of the spirit realm, the shadows of Shiro's past begin to emerge. With each brief awakening of his true self, she loses a little more of him. The fate of the heavens and earth rest in her mortal hands, and she must find the missing gods before time runs out for her world-and for Shiro.
