The breakdown of the black community in order to maintain slavery began with the breakdown of the black family. Men and women were not legally allowed to get married because you couldn't have that kind of love. It might get in the way of the economics of slavery. Your children could be taken from you and literally sold down the river.
The first novel I wrote was a monster - clocking in at 180 000 words - but it died a death a death it deserved. It was called 'The Gods First Make Mad.' It was a good title but it was the only good thing about the book. I didn't let that put me off.
