Midnight's Daughter

Dorina Basarab is a dhampir—half-human, half-vampire. Unlike most dhampirs, though, Dory has managed to maintain her sanity. Now Dory's vampire father has come to her for help again. Her Uncle Dracula (yes, the Dracula), cruelest among vampires, has escaped his prison. And her father wants Dory to work with gorgeous master vampire Louis-Cesare to put him back there. Although Dory prefers to work alone, Dracula is the only thing that truly scares her and when she has to face him, she'll take all the help she can get...
