Emerald Warriors is one of three ongoing Green Lantern titles DC is putting out right now, the other two being Green Lantern and Green Lantern Corps. This is essentially a one shot, a self contained story as opposed to being part of a larger arc. The writer decided to pull back a little bit coming off of the "War of the Green Lanterns" event, which lasted a couple months and spanned all the books.
So what we have here is a bit of good old fashioned spacecopperey starring my favorite Green/Red Lantern: Guy Gardner. Now Guy can be pretty polarizing to GL fans, some hate him because he's too much of a dick, while others love him because he's too much of a dick. I think he makes a great foil for when all 4 earth lanterns are together, because he contrasts their seriousness excellently. Now about the comic. Basic stuff, Guy is going on vacation to rest after war, when he's called to assist a ship of alien dignitaries. He grudgingly goes and helps out, kicks ass, doesn't even bother taking names, and wines and dines the alien princess aboard ship; par for the course for Guy. Then there's a twist. Read the comic to find out.
All in all, a fun entertaining read. Not exactly important if you're worried about story development, so if you're tight on cash you can skip it if you'd like. You'd be missing out on entertainment, but that's all.
