Key to Conflict (Gillian Key, ParaDoc, Book 1)

Meet Gillian Key-a paramortal psychologist who can treat the mental distress of nonhumans. And she's a Marine Special Forces operative who can get physical with them when the situation calls for it. Gillian's two worlds collide when she travels to the Carpathian Mountains in Romania to counsel a dangerously attractive local master vampire-and becomes embroiled in a brewing turf war with the legendary Dracula.
