As of late released Marine sharpshooter John Stewart is at a junction in his life, one which is just confounded by getting an extraterrestrial ring which awards him the powers of the Green Lantern of Earth. Sadly, the ring doesn't accompany directions - however it accompanies stuff, similar to a swarm of interplanetary executioners set on wiping out each Green Lantern in the universe. Presently, with the guide of the happy Green Arrow, Adam Strange and Hawkgirl, this hesitant fighter should travel into the core of a cosmic Rann/Thanagar war and some way or another succeed where any remaining Green Lanterns have fizzled.
