One of the biggest initiatives of World War II was Operation: Firefly--a project so top-secret, not even Captain America was briefed. But how did it involve the super-powered soldiers of the U.S. Army? And why is it still a mystery in the present day, when Cap, its own survivors and even Loki, the Norse god of mischief, are all looking for answers. Join the wartime adventures of the toughest, most exceptional band of soldiers in American military history, in this series by acclaimed writer Paul Jenkins (SENTRY: FALLEN SUN) and rising star Carmine Di Giandomenico (INVINCIBLE IRON MAN ANNUAL, IRON MAN 2.0)!
