She must find the soul collector, Lethe, and enter the deepest, darkest level of the underworld. No one has ever returned alive from the belly of a soul collector, but she will let nothing stop her from going after the precious treasure Lethe stole from her.

Even as she defeats demon spawn and foul creatures of the underworld, strengthening her Vessel power, she still may not be able to save the treasure she loves most in the world.

Meanwhile, the full prophecy hurtles toward the night of the Blood Moon when the Great War between heaven and hell will begin. And demon prince Bamal has a secret weapon. When he reveals it--and guardian angel Thomas reveals his own hidden agenda--Gen may not have the strength to resist the temptation to fall into darkness, forsaking the fate of the world for her broken heart.
