Recently discharged Marine sniper John Stewart is at a crossroads in his life, one which is only complicated by receiving an extraterrestrial ring which grants him the powers of the Green Lantern of Earth. Unfortunately, the ring doesn’t come with instructions – but it does come with baggage, like a horde of interplanetary killers bent on eliminating every Green Lantern in the universe. Now, with the aid of the light-hearted Green Arrow, Adam Strange and Hawkgirl, this reluctant soldier must journey into the heart of a galactic Rann/Thanagar war and somehow succeed where all other Green Lanterns have failed.

While speeding off to help in an impromptu battle, The Flash blazes and rips through time, only to find himself dropped into the middle of World War II. It’s here that The Flash meets Wonder Woman and her top secret team, known as the Justice Society of America. Amidst the raging tides of war, gripping combat and the velocity of valor, The Flash must fight to return to his own timeline.
