City of Night. Odonata, #1

Vampires have nightmares too, and they come in the form of an Odonata. Katrina Templair gave up her human life to become an Odonata-a vampire killer. She's never regretted it, and she keeps looking for one in particular. When she inadvertently rescues Abbey Marquez from a vampire attack, she realizes two things: one, she's close; and two, Abbey is the clingy sort. But Abbey has good information to pass along: the vamps in Los Angeles have become organized human traffickers, and the club they use is a good front.
Determined to stop them once and for all, Katrina gears up for the fight of her un-life. And she vows that she'll take the vampires out no matter the cost. City of Night is the first book in the Odonata Vampire Series. This title contains strong language, sexual situationas, some evil vampire on human violence and perfectly justified Odonata on vampire violence.
