Worried her life might be at stake, the deal she makes could cost her...her heart.

Adrian du Lac is not your average vampire. Nearly 2,000 years old, he's mastered the art of using his immortality to his advantage. Currently living the life of a European businessman, what Adrian really wants is to rule the world. After watching humans screw everything up for so long, he knew it would be easy to exploit their weaknesses. Already, he has set in place a wide-scale plan to take control of all media across all of Europe and Asia. He finally sees his dream materializing when he prepares to collect on a 15-year-old debt stemming from a deal he made with a local Enchanter.

Originally, Adrian sought Katerina Romanov's latent powers. The deal he'd made with her father was simply a means to an end. But now that his protégé has grown into a full-fledged woman, with intelligence and skills he'd not found in a woman before, Adrian's desires take a turn in a completely different direction.

Wanting nothing more than to extricate her family from Adrian's debt, Katerina finds herself drawn to the charismatic vampire, despite knowing the dangers he poses—not only to her safety, but to her heart. Though she plans to play along with him until she can reach her desired conclusion, more unearthed secrets come to light, leaving Katerina confused and angry. With a persuasive man like du Lac, however, she soon succumbs to his charms.

Yet, there are those who fear Adrian will become invincible with the young witch's powers at his disposal. When his enemies set out to destroy him once and for all, he and Katerina run the risk of losing each other forever.
