Skinny B, Skaz and me - John Singleton

Lee's sister, Skinny B, has always been a sickly child, but Lee thinks it's a con. First rule of the family: what Skinny wanted, Skinny got. Lee has plenty of problems of his own, what with trying to get off with Alison, coping with having a friend like Skaz Dutton, who keeps dropping you in it, and all the hassles that go with being fourteen. But then B gets leukemia, and in trying to earn extra money for prezzies, Lee runs into Hoodz5 and the laws of the jungle. It's tough sorting it out, but in the process Lee discovers the real person his sister actually is.
