Zaya faces a terrifying new reality. Morgomoth has trapped her in a sleeping curse, and Zaya's soul has been dragged into the nightmarish underworld of the Dark Divide-a place of endless, shifting tunnels filled with lost, raging ghosts. There is only one way out. A door that, if opened, will unleash the Dark Divide into the living world. Morgomoth has given Zaya a choice. Open the door, join him and his evil forces, or remain trapped for eternity. Zaya must do the impossible. Escape from the Dark Divide, save Jad and her friends from Morgomoth's horrors on the world, and learn to defeat him using necromancy. But it won't come without sacrifices... or betrayal.
