Deadly Unna?

'Deadly, unna?' He was always saying that. All the Nungas did, but Dumby more than any of them. Dumby Red and Blacky don't have a lot in common. Dumby's the star of the footy team, he's got a killer smile and the knack with girls, and he's a Nunga. Blacky's a gutless wonder, needs braces, never knows what to say, and he's white. But they're friends... and it could be deadly, unna? This gutsy novel, set in a small coastal town in South Australia is a rites-of-passage story about two boys confronting the depth of racism that exists all around them.
