How does Niya change over the course of the story in the novel, Ghost Train?

Niya is much more open-minded at the end of the novel than she was at the beginning, partly because Remi's point of view has somewhat expanded her own. Further, his treatment of her as an equal has encouraged her to take an active role in pursuing justice—in the process giving her more selfconfidence and helping her to discover her own fortitude and courage.
