Green Lantern : Earth One. Volume two
(Graphic Novels & Manga)

"Hal Jordan and John Stewart must team up to save the last Green Lantern Guardian from an evil force! Manhunters, alien races, rings of power--it's a lot for the people of Earth to absorb. Especially when an interplanetary incident forces their protector, Hal Jordan, to leave on a rescue mission that results in the discovery that there's a new player in the galaxy: Yellow Lanterns! While they seem a benign force for peace, Jordan can't get comfortable with how much power they wield, or their bizarre, lockstep behavior. When fellow Earthling John Stewart ends up with a yellow ring, he and Hal must work together to confront the being who destroyed the original Green Lantern Corps--the last surviving Guardian."--Provided by publisher.
