As World War I breaks out, the arranged marriage of Mary Matroona, an 18-year-old Aleut girl, to Sean Calhoun, an Irish immigrant, begins a story of enduring human spirit and the power of love to break through every barrier. This young couple, strangers to each other, settles on an island called Unalga, located on the remote eastern rim of the Aleutian Chain of Alaska. As their adventure begins, so do their troubles and struggles. As the months roll by, they discover their own strengths and weaknesses, a need to know God, and their love for one another. Stranded with few supplies, attacks from a poacher, and nearly losing each other to death, they discover something sacred during that season on Unalga.
