The Divided City by Theresa Breslin
Published by Corgi

Graham and Joe both live for football; they are talented, and play well together – their dream is to be picked for the Glasgow City team. The only thing is that they come from different backgrounds – Graham is a Rangers supporter whose Granda wants him to take part in the Protestant Orange Walks; Joe’s family are Catholic. The boys just want to play football, but the old rivalries keep surfacing. What is more important, the religion or the game?

Then, taking a short cut home from football practise one night, Graham’s life is changed dramatically. He witnesses a gang knifing a young man, and has to decide whether to get involved or take the easy way out. This leads to him and Joe forming an unusual alliance off the pitch, to help Kyoul who is an asylum seeker, and to questioning what is really at stake for Glasgow as a city. Their friendship is put to the test, and they have to decide what really matters to them.

Very thought provoking, especially if you are into football.
