They've betrayed their worlds, but they will never betray each other.
After Mick unearthed Waapikoona from the grave, he didn't expect to lose her again to an unnatural endless slumber. Without her, he can't navigate his new duties-and the chaos-she brought upon him. He can't appeal to the great demon who can revive his baby niece from the dead. And he certainly can't save the world.
Waapikoona feels the underworld retreating from her bones, and it's left her with more than just a nightmare. Not long ago she yearned to see the upperworld in flames. Now there's too much for her to lose. Torn between two worlds, she must make a choice: join the mutiny against her creator or ally with Mick-and everything he stands for.
Between underworld-corrupted sky and earth, in black water churning with demons, an eagle clashes with a great demon as an undead woman and her sister fight to save time itself.
