DC Comics released Green Lantern #33 earlier this week. There are four stories in this oversized issue. Here is the official summary:
"In this special, oversize 600th issue, Hal Jordan will be tested as never before… and a new Lantern stands poised to step in should he fail. Hal embarks on a mysterious mission while Kyle Rayner finally moves back to Los Angeles and again takes up the mantle of Green Lantern of Earth. Join Kyle as he finds a job, navigates traffic, and chases down escaped villains from Oa! All this, plus a host of legendary guest artists and writers from Lanterns past, and an answer to the question posed to Star Sapphire in the last issue."
