Possession by Armintrout, Jennifer. mass_market edition. ISBN: 9780778324188.

My father always said fear was a weakness. Well, thats easy to say when you dont have to worry about vampire slayers or holy water. I hate fear, but undead life goes on. In the two months since I was attacked in the hospital morgue and turned into a vampire, Ive killed my evil sire, Cyrus, fallen in love with my new sire, Nathan, and have even gotten used to drinking blood. Just when things are finally returning to normal—as normal as they can be when sunlight can kill you—Nathan becomes possessed. And then he slaughters an innocent human. Now its my job to find Nathan before the Voluntary Vampire Extinction Movement does, because theyre just waiting for an excuse to terminate him—and anyone foolish enough to help him. But it gets worse. It turns out that Nathans been possessed by one of the most powerful and wicked vampires alive—the Soul Eater. And who knows what vile plan hes concocted? With the Soul Eater and my possessed sire on the loose, I have a lot to fear. Including being killed. Again.
