"While exploring Michigan's Pictured Rocks National Lakeshore Park, twins, Ben and Bekka Cooper, along with a new friend Eli, discover not only the beauty of Lake Superior, but encounter more than they bargained for. With keen eyes and quick thinking, they came upon thieves planning to steal artifacts from sunken ships. Needless to say, their vacation was more than just a camping trip."--Back cover.
