Book excerpt: From the Publisher: Edge of Empire provides both an overview and an intensely detailed look at Michigan's Fort Michilimackinac at a very specific period of history. While the introduction offers an overview of the French fur trade, of the place of Michilimackinac in that network, and of what Michilimackinac was like in the years up to 1716, the body of the book is comprised of sixty-one French-language documents, now translated into English. Collected from archives in France, Canada, and the United States, the documents identify many of the people involved in the trade and reveal a great deal about the personal and professional relations among people who traded.
