Meet Annette Anderson. Once she was a young beauty living in the heart of York, England, who became infatuated with a boy all the girls sought after. She followed him everywhere and basked in his attention, until one night he stole her innocence in an alleyway and a world of darkness swallowed her whole.
From that night she had begun to see the creatures of other worlds. Their deformities and unnaturalness drove her to the brink of madness. They followed her, plagued her dreams and whispered evil doings in her mind.
Her parents wouldn't believe her when she begged them for help. Her perfect little sister was too young to understand. And so, she fled. Making her way to London, tracking down a demon owned bar and meeting a demon who would change her life for ever.
After succumbing to a drug promised to save her tainted soul, Annette is weakened and a presence invades. Lilith, an ancient and powerful demon wishes to possess her. The blonde seductress, Lilith, is entrapped when Annette proves too powerful to own, her human soul refusing to leave. Instead, they are forced to reside together in an uneasy relationship. The first years of their cohabitation are ones of blood and slaughter, of fights for control. A battle Annette must strive to win daily. After decades of hardships they work for balance. All the while they know both of their souls belong to another world, to another demon deep beneath the surface of the mortal world. They belong to a Prince of Hell who requires them to bring home his escaped demons before they enlighten humans to their existence.
A spate of murders plague London, forcing Annette out of her newfound peace. Detective Michael Daltry seeks her out when all those he asks for help whispers her name. She is known as the Living Demon to most supernatural beings and Human Whore to those who believe she is an abomination, a joke to demonkind. In Michael's presence, Lilith is somehow unable to gain any control. She barely has the strength to whisper to Annette when he is close. Annette is drawn to whatever power Michael might have and soon begins to wonder if there is far more to him than even he knows.
After denying the Prince's calls for Annette to return to him and more demon murders occuring, Annette is ordered to the Hellworld Lilith's souls belongs to. Her master, the Prince, tells her to find the demon murderer and bring him back for punishment. He sends Rowan, an Incubi demon, to escort her and help her until the demon is caught. He is also to watch over her in the eventuality that Annette decides to flee or ignore her orders. Rowan is intrigued by Annette's ability to hold within her two souls, a human and a demon, and survive to tell the tale. But there are strengths Annette possesses unknown to her. There is a rare gift once thought wiped out by the Princes for it threatens their kind. It is only Annette's passion and strength and her ability to pull allies to her, that has kept her alive so far. But, Annette is soon to learn the truth of what she is, of what this could mean and unknown to her are the Powers above and below that are playing their own games with her soul.
