She is ninja and goes after the men who had killed her family and tortured her and her sister (her sister is dead, by the way). She soon learns to feel again by the vampire, and even falls in love with him. Soon, she must choose whether to kill the top dog, or live as a normal young woman.
The novel about Half Dragons is about two teens who soon learn they aren’t exactly human. One becomes blinded permanantly but learns to see in other ways. The other has the power to destroy the cosmos. Both must soon choose whether they will save humanity… or destroy it.
