Zoe is a succubus with an appetite so strong she can even kill immortals. She makes use of her unnatural Hunger by working as a seductive assassin for the governing Tribunal. But a year ago, she fell for a human and accidentally lost control in the throes of passion, killing Griffin Morrow. Since then, Griff's ghost has been her involuntary companion--a witness to her dark, erotic encounters and a constant source of guilt. Before becoming a phantom only Zoe can see or hear, Griff was a lawyer with a strong sense of justice. When a sorceress brings him back to life on the condition that he kill Zoe, can he rationalize her death as self-defense? Or will the chemistry between them and his growing feelings for the surprisingly vulnerable succubus cost him his second chance? This erotic romance novella is a standalone read but takes place in the same fictional world as A WICKED HUNGER (available now) and the upcoming WICKED PERSUASION. less
