It's been 10 years since the triumphant return of Chuck, his family, and his fellow settlers to a new, post-nuclear-war Alaska.
It's been nine years since the UN recognized Alaska as a new nation under United States protection.
Now, a struggling United States has abandoned them again.
Good people have died. New enemies have arisen. And once again, Chuck is faced with dragging a new Alaska, kicking and screaming, into the modern era.
It won't be an easy road. Chuck is still struggling with the death of his wife. Resources have dwindled to nearly nothing. And though he has the strength of his growing children to rely on, the way forward is difficult - almost hopeless.

Along the way, Chuck and his followers will see who their real friends are. He will understand the value of sacrifice and the true meaning of bravery once again. And he will learn, and teach, a single, hard, essential lesson:
You can only rise as high as you're willing to imagine.
