Protector: The Firestone Family finds that with increasing powers come increasing responsibilities, and also increasing threats. Protector follows the career of TiiNa Firestone, hybrid daughter of Greg Firestone, a human male, and NaDii Ix ChiiBi, a HaChii female. As she and the other members of her family develop new superpowers, TiiNa finds that she must not only convince the residents of her father's home world of her worthiness to live in it, but to let her and her family protect it, and all the worlds of the Human-HaChii Alliance.
