Midnight Reign (Vampire Babylon, Band 2)

"Night Rising" was only the beginning... Dawn Madison reluctantly came to Los Angeles in search of her missing father and found instead a world of murder and the living dead she never imagined existed. When a new vampire slaying lures Dawn deeper into the underground, her alliances in the sunlit world shift. Now she has only herself to trust and her new found skills as "a spunky vampire slayer" ("Publishers Weekly").
