Thinned out blood

Rebecca was sent away as a guinea pig because her parents didn't think she was worth anything. After she was helped out, she was supposed dead by the people at the facility, and took the name Jessica, trying, but not succeeding in hiding her now vampiric nature. Fate made it so that the school she then attended included a crazy, vampire hunting teacher and her cousin, not making her new life easy. On top of all that, the vampire that got her out of the testing-facility has also left her basically to her self when it comes to survive as a vampire, not that Jessica complains. She's tough and ready to fight for what she believes, driven by the pain of being abused and neglected at the facility, but of course, some things has to go wrong.
