A young man lies bleeding in the street. It could be any street, in any city. But it's not. It's Glasgow. And it's May - the marching season. The Orange Walks have begun. Graham doesn't want to be involved. He just wants to play football with his new mate, Joe. But when he witnesses a shocking moment of violence, suddenly he and Joe are involved. With Catholics, and with Protestants. With a young Muslim asylum-seeker, and his girlfriend. With all the old rivalries - and fears . . . A gripping tale about two boys who must find their own answers - and their own way forward - in a world divided by differences.
