Turned By Blood [Supernaturals Underground, Book 6] - Supernaturals Underground, #6

When you're the only regular human in a social circle of Mages, vampires, and werewolves who are busy saving the world from demons, feeling left out is a given. I'm just the girl who does research and takes phone calls, all while hiding my double life from my Supernatural-hating mother. Well, I was the only regular human. After an accidental bite from my best friend, I find myself a newborn vampire.
If this gets out, school will expel me, my mom will kick me out, and that treatment center who rounds up Supernaturals and never lets them out again? They're still around, so I've got to dodge them, too. Oh, and it gets worse. When I bite someone who just might be a god, my new powers heighten to the point where I draw the attention of the first vampire. And she's got a terrifying future lined up for all the vampires along with humanity.
When I land in the center of that plan, it's official: I'm not just the errand girl anymore, and boy, I wish I was.
