Harley believed capturing the djinn would bring peace to the Sanctuary, but fate has other plans. A new, magical plague threatens the fae community-a dark and untamed magic resurrecting the dead and decaying the living.

When eerie, trumpet-like calls awaken her in the night, Harley senses a demon presence chasing ghostly animals through Midway City. With the phantom stampede growing more corporeal and destructive each night, Harley must uncover the source of this chaos.

Her quest leads her to an old circus elephant graveyard, where she discovers a darkling lord tied to ancient, malevolent powers. This darkling, with hellfire in his eyes, threatens to unravel everything Harley has fought for.

In a race against time, Harley sees the shadow of her enemy-the Priest-looming ever closer, preparing to destroy everything and everyone she holds dear. With the Sanctuary's survival hanging in the balance, Harley must summon courage and her inner demon to confront the rising evil in a world where the line between life and death is hauntingly thin.

Will Harley find the strength to protect the Sanctuary and her band of misfit fae, or will the darkness claim them all?
