Green Lantern - Sector 2814 Vol. 03 (2014) (digital TPB)

In this new collection of 1980s Green Lantern adventures, John Stewart clashes with Guy Gardner to see who will be the Green Lantern of Earth. And while Stewart battles Harbinger during the Crisis on Infinite Earths, Gardner recruits enemies of the Green Lantern Corps to stand against an evil that could destroy the entire universe–including The Shark, Hector Hammond, Sonar, Goldface and more! As the two factions fight each other–John Stewart and the Green Lantern Corps vs. Guy Gardner and the villains–a fallen Lantern's ring finds Hal Jordan, who reclaims his place in the Corps.
