All hail the king and queen of Hell.

Two curses. One prophecy. A reckoning all have feared. And a love more powerful than fate . . .

From the #1 New York Times bestselling author of the Stalking Jack the Ripper series comes the dazzling conclusion to the Kingdom of the Wicked trilogy.

Emilia is reeling from the shocking discovery that her twin sister, Vittoria, is alive. But before she faces the demons of her past, Emilia yearns to claim her king, the seductive Prince of Wrath, in the flesh. Emilia doesn't simply desire his body, she wants his heart and soul - but that's something the enigmatic demon can't promise her.

When a high-ranking member of House Greed is assassinated, Emilia and Wrath are drawn to the rival demon court. Damning evidence points to Vittoria as the murderer and she's quickly declared an enemy of the Seven Circles. Despite her betrayal, Emilia will do anything to solve this new mystery and find out who her sister really is.

Together Emilia and Wrath play a sin-fuelled game of deception as they work to stop the unrest that's brewing between witches, demons, shape-shifters and the most treacherous foes of all: the Feared.

Emilia was warned that when it came to the Wicked nothing was as it seemed. But, have the true villains been much closer all along? When the truth is finally revealed, it just might end up costing Emilia her heart.
