The world is cursed. A monstrous fog consumes and remakes all things infected with the black fog. A community of Seers push back against the curse. These seers are all women who have been orphaned. They live and train together in an ancient temple past the bone labyrinth. They perform elaborate and beautiful rituals to appease the ghosts of the world, and hold back the tide of the curse.

Their leader, Naomi, is missing.

Mazi, her adopted daughter, and her friend, Talia, embark on a dangerous quest to the center of an infected city, seeking out their lost mother. Without knowing it, they enact a deadly drama as old as time, where ghost hearts, curses, wicked prophets, and seers, all wrestle with the fabric of reality, itself.
