What is the main conflict in Dust Tracks on a Road by Zora Neale Hurston?

This is an autobiography of a highly articulate African-American woman. She is the daughter of the Mayor of an "all Negro" town; this was a political and social intentional experiment. There was support for the endeavor from the white community; the author carefully and honestly acknowledges this. She has two married parents to start out with, but during her childhood her mother dies. When her father remarries, there is a great deal of trouble as her stepmother does not truly embrace the children. The remarriage is destroyed when Zora wins a brawl with her stepmother and to the woman's horror, Zora's father does not intervene. The woman leaves him after that. After this event, the man's children are somewhat scattered, though not entirely lost. They are somewhat forced to make their way prematurely in the world.
