Poison Blood, Book 1: Revelation (Poison Blood Series)
"I don't know what blood tastes like to a human. I'd never even licked a tiny drop of it from a pricked finger, let alone suck on a bleeding cut. The shedding of blood, my own, or anyone else's, always made me scream or panic in fear and revulsion. Now it's my only food source." Ellie is not a typical teenaged vampire. She still has her humanity and conscience. And the same distaste for blood.
