I'm told this is the best place to start reading modern Green Lantern comics. Shall we begin?
Today we learn that the GL Corps has been around for billions of years (really?), "until one of their own destroyed it all." This is referring, I suppose, to the Parallax thing--I never read those stories, but I'm vaguely aware of what happened.
...which is more than I can say for this story. There's a lot of stuff. Metamorpho's helping out the Justice League? I have no idea what he did, after his origin story. Stories. Whatever. Guy owns a bar? John's a Green Lantern... but didn't the story say that the GL Corps was destroyed? I don't know enough about what happened. Green Arrow has a spare GL ring laying around. I just... there's too much stuff, here. I guess I'll have to read on, and see if it all makes sense in retrospect.
