It was a time of international tensions, a time of hope and fear—when Elvis, Howdy Doody, UFOs, and the Communist menace preoccupied America. It was the first time in history when human beings had the power to destroy their world. A time when heroes were needed more than ever. Evil is loose in the world. As the United States and the Soviet Union race to build their nuclear stockpiles, two extraordinary men are called upon to form an uneasy alliance. Studies in opposites—shadow and light—a Dark Knight and a Man of Steel must overcome their mutual distrust to battle a darkness that threatens humankind. And when the paths of these titans cross, a bold and exciting new chapter of history will be written . . . and nothing will ever be the same.
