School is almost out... and Canada, Britain and the United States are on the brink of war over the Alaskan border. This doesn't mean much to Kip and Aurore, until a deadly explosion at the Star Mine throws them into a swirling adventure involving coded telegrams, burgled hotel rooms and President Teddy Roosevelt ... and a mysterious German naval captain named Oskar von Neidling.
