Avatar Volume 6: The Last Airbender

When Aang and company arrive in a small Earth Kingdom mining town that is controlled by the oppressive Fire Nation, they cross paths with a young boy named Haru, who keeps hidden a powerful secret for fear of being arrested. But the Fire Nation gets wind of this newly formed alliance, and the entire gang is thrown into a remote prison--with no escape in sight. Will Aang's destiny to save the world finally be sealed...forever?
