Arthur Thurner tells of the enormous struggle of the diverse immigrants who built and sustained energetic towns and communities, creating a lively civilization in what was essentially a forest wilderness. Their story is one of incredible economic success and grim tragedy in which mine workers daily risked their lives. By highlighting the roles women, African Americans, and Native Americans played in the growth of the Keweenaw community, Thurner details a neglected and ignored past.

The history of Keweenaw Peninsula for the past one hundred and fifty years reflects contemporary American culture—a multicultural, pluralistic, democratic welfare state still undergoing evolution.

Strangers and Sojourners, with its integration of social and economic history, for the first time tells the complete story of the people from the Keweenaw Peninsula's Baraga, Houghton, Keweenaw, and Ontonagon counties.
