Cry, the Beloved Country

I was impressed with the book in high school. But then, that was the 60's and racial upheaval and social unrest was rampant in our country as well as South Africa. I am re-reading this poignant novel now as a parent in this new century of continued world-wide unrest.
The story of a father searching for his son who has left the simple village life to be swallowed up in the moral and social turmoil of Johannesburg who questions what has gone so wrong that his own child (as well as his adult sister and brother) would succumb to the evils of the city. The pain is real, the anguish cuts deep, yet the father continues on. As he searches he faces the fear of the unknown. As he uncovers the layers of sin, he fears the worst only to find his fear confirmed. His fear turns to sorrow.
He is comforted: "Sorrow is better than fear. Fear is a journey, a terrible journey, but sorrow is at least an arriving."
"When the storm threatens, a man is afraid for his house... But when the house is destroyed, there is something to do. About a storm he can do nothing, but he can rebuild a house."
How do you go on when you discover the worst - that your child has turned away from simple Christian upbringing to the indulgences of the world? The father finds comfort in an innocent child, the product of the nightmare of sin.
I'm only halfway through the book.
