Grass by C.Z. Nightingale
Sixteen-year-old Caryn witnesses a savage attack on an Asian boy by a white gang in East London. She doesn't know what to do as grassing is not the done thing. When Kobir, the victim, later dies, she can't avoid being involved. Should she grass or should she stay silent? The story reaches a dramatic climax and Caryn must learn to trust her own judgement of right and wrong.
