Green Lantern Corps #22

KRONA RETURNS! Guy Gardner and Kyle Rayner have entered the Well of the Emotional Entities in a desperate attempt to find Hal Jordan, who is lost in the universe following a cryptic hint from the Book of Oa. They'll need the new chromatic Alpha Lanterns to work together and manage their powers to face what's on the other side: the decrepit surviving Guardians of the Universe and the monstrous reborn Krona!
