Vampire's Tale

Her mother died giving birth to her, so her vampire father had to raise her. One night her father never came back to the cave that they were staying in that night. A strange man came into the cave and injected her with something. She awoke in her "uncle's" castle where they raised her until her teen years when she left. Her vampire half took over, and she gained many powers quickly. She had to go from place to place, town to town, because she was constantly being hunted.
