The Last Enchantress — Scott Powell; Judith Powell

Being nineteen for over three hundred years bites, and being single in New York with magical powers isn't much better. Eva is trying to live an everyday life in New York. When this fails, she takes a seemingly unmagical job as a translator for a wealthy American family in Spain. Eva cannot stay out of trouble for long as she runs into a friendly but hungry vampire named Louis. Eva feels drawn to this handsome, dangerous stranger who has problems of his own. Louis's life was just fine until Eva walked into his church. She smells like heaven. Or is it hell, always smelling but never partaking? Surely she is the devil coming to collect on his lost soul.
