This is a compilation of several issues of the Green Arrow comic book series. The thing that makes these particular issues special is the fact that it was written by Brad Meltzer ("The Millionaires", "The Zero Game", etc). This is one incredibly amazing book! Green Arrow has just come back from the dead (don't they all?) and now has some unfinished business to take care of. Along the way, we see the return of a grown-up Speedy (now Arsenal) helping GA collect artifacts from his life. Most are surprising, and a couple are very puzzling as to their meaning--until the end of the book. I don't want to go into details because that's part of what makes the story so great.
We get to see a new side of the Emerald Archer here too, with a return to the things of the past that can bring back some memories for those of us who read the old series and remember his original JLA days. At one point, he even takes on Solomon Grundy with nothing but his bare hands and two arrows (you've got to read it to believe it--it's incredible!). As an added bonus, you get the script to the first issue, as well as Brad's original pitch for the storyline (it's different from the book, and it's good that he improved on it for the actual series).
All in all, I can't recommend this one highly enough. It's got everything you could ever look for in a comic book story, including the most startling plot twist ending I've read in a long time. That one panel changes everything we've known about GA's past. You definitely want to read this one, and I hope Brad comes back again sometime to write a few more!
