The battle for the Aleutian Islands during World War II has barely made it into the history books. But now, it's the subject of a new novel. "The Wind is Not a River" tells the story of a war correspondent who becomes stranded on the Japanese-held island of Attu, and his wife's efforts to find him in the sweeping Alaska Territory.

In this segment of "The Exchange," author Brian Payton walks through the historical research -- and visits to the Aleutians -- that went into his new book.
