Despite the successful management of her coffee house, Bianca finds that her love life is lacking such accomplishment. With each step the other horsemen of the apocalypse take toward happiness on earth, Bianca allows her fears to hold her back. But as Mistress Lethe, a simple woman and the embodiment of Conquest, Bianca finds a man who sees all of her: the light and the dark…. even if is only for a little while.

New to the Big Apple, Victor Brandt realizes that the sweet touch of diversion is almost a necessity. He just never expected to find it behind a red door. As The Underworld embraces him like silk, he realizes there is no going back. Night after night he returns just to see Mistress Lethe: a Dominatrix so demanding she will satisfy her submissive into forgetting their own name before stealing her pleasure. But when his dark Mistress draws him into her world, Victor realizes that the dangerous games they play have become all too real.

With a mysterious stranger bearing ill omens, and visions of the future threatening everything the horsemen have built, Bianca is faced with a cruel joke played by fate, a decision that can save the world but will cost her the first man that’s ever made her want to be human.

Can Bianca detangle the strands of fate and love? Or will she succumb to the pressure of her mantle and be forced to watch as Hel brings about the Apocalypse?
