" The hardcover book was an academic monograph from a Midwestern university about the Battle of Kursk. Kursk happened in July of 1943. It was Nazi Germany’s last grand offensive of World War Two and its first major defeat on an open battlefield. It turned into the greatest tank battle the world has ever seen, and ever will see, unless people like Kramer himself are eventually turned loose. "
