Karen Chance - Dorina Basarab, Dhamphir series

Dorina Basarab, Dhampir 01 – 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.

Dorina Basarab, Dhampir 02 – Death’s Mistress: Dorina Basarab is a dhampir - half-human, half-vampire. Back home in Brooklyn after the demise of her insane Uncle Dracula, Dory's hoping her life is about to calm down. But soon Dory realizes someone is killing vampire Senate members, and if she can't stop the murderer, her friends may be next.

Dorina Basarab, Dhampir 03 – Fury's Kiss: Dory is used to fighting hard and nasty. So when she wakes up in a strange scientific lab with a strange man standing over her, her first instinct is to take his head off. Luckily, the man is actually the master vampire Louis-Cesare, so he’s not an easy kill. It turns out that Dory had been working with a Vampire Senate task force on the smuggling of magical items and weaponry out of Faerie when she was captured and brought to the lab. But when Louis-Cesare rescues her, she has no memory of what happened to her.
To find out what was done to her—and who is behind it—Dory will have to face off with fallen angels, the maddest of mad scientists, and a new breed of vampires that are far worse than undead...
