Double Cross - Malorie Blackman

Everyone assumes the bomb that killed Callie Rose's grandmother was the work of a nought terrorist. But Callie Rose knows the truth - and her fear of the past leaves her afraid for her future.

Her boyfriend Tobey is worried about his own future. A nought boy at an exclusive school, Tobey hopes to keep out of trouble, go to university, get a good job and leave the dangerous streets of his childhood behind. But Tobey is discovering that he can't keep clinging to some kind of no-man's land while the neighbourhood around him is carved up by rival gangs. Then he is offered the chance to earn some ready money just making a few 'deliveries'. He doesn't want a part of that world, the world of gangs. But maybe he could get away with it, just this once . . .

He little realizes how his decison will bring violence down on both himself and Callie and just how far he will go in fighting back....
