Welcome to the Kingdom of Hades, where even its prodigal princess sleeps lightly. After fighting Soul Stealers in Detroit, Khara hoped to return home to find answers in her father's realm. But the land of the dead offers little information, and far too much tragedy. Now cut off from her brothers, and left only with her dark and unreliable companion Oz, Khara must navigate the centuries-old webs of deceit and betrayal, all while eluding the Underworld's most depraved inhabitant. But she soon finds an unexpected ally in her adopted sister Persephone. Together, they endeavor to right a terrible wrong. And as Khara soon discovers, there's more riding on her success than she ever thought possible.
