A century ago a portal opened over Central America and the Tetza that came through changed our world. Now the world bends all its effort to making the Iron Kings--great mechs that must battle the Tetza for humanity's continued survival in gladiatorial combat. Anita Marr is the greatest of the pilots and is chosen to pilot a new prototype that could change the tide in humanity's favor.

A story of heroes, impossible armors, ghosts and two people, centuries apart, connected by their need to protect the ones they loves.
