New book details a previously unknown 'glamping' trip to the Boston Harbor Islands in July 1891

Back in July 1891, four women from Lowell took a trip to the Boston Harbor Islands. They left their family and children for more than two weeks, and documented the entire thing. That journal was recently found in a used book store, and for the first time the women's experiences - and their identities - were discovered. Those details are the subject of a new book called "A Boston Harbor Islands Adventure: The Great Brewster Journal of 1891." We speak with the book's author, and the woman who helped lead the research effort.
