Rapture's Edge (Night Prowler)

Eliana is a woman on the run. As a Shadow Walker, she is driven from her home in Rome when she believes the man she loved murdered her father. Now she makes her living as an art thief and a competitor in the underground fighting circuit of Paris. But her past is about to catch up with her in the form of The Hunt, a group of elite assassins with one objective: eliminate her before she can expose the secrets of her shape-shifting clan to the world....

Demetrius is a man with nothing left to lose. Haunted by the memory of Eliana and the passion they once shared, he will risk everything to save her from the killers on her tail. He must convince her, before the ancient walls between two worlds crumble, that only together can they defeat their real enemy, a brilliant, cunning traitor far more deadly than either of them can guess.
