In an attempt to gain power over the borders between the Outer and Inner planes, Adiran Martinique locked his daughter inside the Abysmal Throne with the intention of using her as his puppet. With the borders between the planes closed, Zoë was cut off from her friends and family. Alone. 
What he didn't count on was his daughter receiving help from an ancient consciousness that has existed for centuries. Now this entity has promised her a way to break the bonds of the Abysmal Throne and return physically to the Physical Plane and her lover, Dags McConnell. 
But should Zoë trust this voice in her head? The last person she trusted was her father—and look where that got her. The Ethereals are after Dags for the magical tome fused to his soul, and in order to protect him, Zoë has to make a choice to trust the Geist to escape or truly become the Phantasm of the Abysmal Plane.
