Green Lantern : Earth one. Volume two
(Graphic Novel)

"Earth is no longer alone in the galaxy, but not everyone is ready for company. When Earth Central Command is accused of attacking a LLaran spaceship, Hal Jordan does his best to repair the breach--and rescue the scientists and diplomats taken hostage in the aftermath. But he comes up against an even deadlier force: a new enemy wielding powerful yet strangely familiar technology. These new Yellow Lanterns are fighting the same Manhunter menace as Hal's allies in the Green Lantern Corps, but what do they really want? When fellow Green Lanterns trade their membership in the Corps for the new, more powerful rings created by the Guardian, Hal is skeptical. And when the Yellow Lanterns attack, loyalties are torn apart just as they become more important than ever."--back cover.
