The Chalice: Luna Vampire Series (Book 1)

Luna Lynn Miller awakens to find herself naked and freezing in the pitch black nothingness of a cement pit. Instantly panic stricken, she discovers that blood is steadily seeping from several deep cuts on her neck and wrists. Mysteriously elusive, her captors give her a choice; she can either drink a supposedly lifesaving concoction from their chalice or die. Now, there's one thing you must understand about Luna, she's no shrinking violet. And she won't stand for scare tactics or manipulation. Beyond that, she's dead set against cooperating with her kidnappers. Nonetheless, Luna's in for quite an adventure when she discovers that her future's irrevocably intertwined with the world of the vampire aristocracy. Will she give in to their demands or choose her own path?
