The Jaz Parks Novels by Jennifer RardinRead about the other entries on the list.
I recently wrote a blog post praising Rardin, who was one of the bigger names in urban fantasy as it was exploding during the mid-‘00s. Her series is about two CIA assassins, a butt-kicking, mouthy female narrator and her centuries-old vampire partner. There’s some great worldbuilding here, and the espionage/CIA angle provides a fresh twist to a popular format.
