Green Arrow and Black Canary, Vol. 2: Family Business

After years of dramatic on again, off again romance, Green Arrow and Black Canary finally combine forces in their own world-spanning superhero series as the two lovebirds search for GA's kidnapped son, Connor Hawke.
With Ra's al Ghul's criminal cabal, the League of Assassins, behind an assassination attempt on Connor and his subsequent abduction, Green Arrow and Black Canary enlist the aid of guest-stars Batman and Plastic Man to save the young hero's life. It's ninjas versus superheroes in a last-ditch effort for survival and when the smoke clears, the Green Arrow family may never be the same.
