Immortal Temptress. Devil's Promenade, #1

Enya's job is to escort the dying on their final journey, to make sure their souls get to heaven before a demon can steal their bodies. For centuries she has done this without emotion, until the body in question belongs to Kane Sullivan. Not only does she desire his rock-hard body, she can't bear the thought of him dying. But she's not supposed to become emotionally involved in a death. Kane's sudden run of near-fatal accidents always happen when Enya is present.
She might be hot, but he's not willing to die to get to know her. Then he discovers she's fighting for his soul. That damned immortal temptress might be the death of him.
