Burning Bright by Barry Levy

Danny Rothbart is good-looking, bright, popular teenager living in Yeoville, Johannesburg, in the seventies. It seems he has the world at his feet - except for one little problem. He's having trouble losing his virginity, and the shame of the situation threatens his world. Unable to talk to his old-fashioned parents, Danny seeks guidance from the one adult in his life he can trust: charismatic, politically liberal Uncle Harold. But the suave, worldly Uncle Harold has another agenda. He is a serial child molester, and soon he draws Danny into a sickeningly manipulative abusive relationship.
