Blood Ties by Karen E Taylor
Deirdre Griffin was perfectly content to remain where she was for a while. She had the love of her life by her side and part-ownership of a bar which served up tourists for sustenance. But she and Mitch are asked to return to NYC, to deal with a psychotic vampire who now threatens the members of the Cadre collectively and Deirdre specifically. Deirdre and Mitch must join forces with their former enemies to capture the killer.
