Green Arrow, Volume 5: The Outsiders War

Oliver Queen thought he had it all figured out. As the heroic archer Green Arrow, he'd finally found a sense of purpose, friends to aid him, even a place on the Justice League of America. But now, he's not even sure where he came from... or who he came from.
As Green Arrow discovers that his stranding on a desert island was more than just an accident, there seem to be more sinister forces at work behind all these sudden revelations. The Queen family is embroiled in a war generations old. A war of clans.  A war of outsiders.
Acclaimed creative team Jeff Lemire (Animal Man) and Andrea Sorrentino (I, Vampire) take Green Arrow on his most challenging adventure yet.
