Reddit mentions of Green Arrow Vol. 6: Broken (The New 52)

I would recommend starting with Green Arrow:Year One by Andy Diggle. It modernized his origin and is what the island flashbacks were roughly based on.

Then I would move to the best Green Arrow run from the New 52 by Jeff Lemire which can be found in Volume 4: The Kill Machine, Volume 5: The Outsiders War, and the first half of Volume 6: Broken which releases in May.

I would also recommend Green Lantern/Green Arrow by Denny O'Neill & Neil Adams, as it was the original run that modernized the character.

As for other characters from the show appearing in the New 52, Roy is a main character in Red Hood and the Outlaws along with Red Hood (Jason Todd, the second Robin) and Starfire. Laurel was also the leader in Birds of Prey, but I never read it so I don't know if it's good or not.

Edit: And for a good Ra's al Ghul story I would check out JLA: Tower of Babel.

Additionally, Amazon Claus has posted other solicitations for Justice League Vol. 6, Wonder Woman Vol. 6, Superman: Doomed, Justice League United Vol. 1, Earth 2 Vol. 5, Earth 2: Wold's End Vol. 1, Superman/Wonder Woman Vol. 2, Batman/Superman Vol. 3, Green Arrow Vol. 6, Green Lantern Vol. 6, and Harley Quinn Vol. 2.

You see the third trade? They couldve wrapped it all in 2.http://www.amazon.com/gp/aw/d/1401254748/ref=mp_s_a_1_1?qid=1413251518&sr=8-1&pi=AA75#productDescription_secondary_view_pageState_1413251539938

Okey, so this is (obviously) my opinion but I'd start reading in this order:

• Year One
  
• Kill Machine
  
• The Outsiders War
  
• Broken
  
  And then move on to Green Arrow Rebirth run which is the newest and ongoing run. You can also continue the run after Broken but in my opinion it was pretty meh. Rebirth has been great though. Don't read any super old stuff at first, comic fans like to recommend that stuff but it's not for most beginners.
