Alaska was a frozen wilderness stretching from end to end. There, several tribes lived and struggled against a realm of silence, cold, and hidden dangers. Yet the arrival of Japanese forces invading the Aleutian Islands shattered a quiet that had endured for thousands of years.

The Aleutians would not be enough. Sooner or later, his sacred birthplace and the people he cherished would become trophies for them.
