The "land in between" is the upper St. John Valley, a region straddling the MaineNew Brunswick border. A zone of contacts between different Native American cultures until the arrival of the Europeans, it was disputed by the British and the French in the colonial period and settled by Acadians and French Canadians in the eighteenth century. To this day, it has remained the site of a distinct FrenchAmerican culture, and its residents have striven to preserve their specificity and unity despite the international boundary. The Land in Between is a narrative survey history of this fascinating and unique region and is also designed to serve as a reference for teachers, librarians, archivists, and historians. It includes documents (many translated from the original), maps, and an extensive bibliography. Batrice Craig holds a PhD in Canadian-American history from the University of Maine.
