Delta Wedding by Eudora Welty; 1946/1979. Softcover.

Set on the Mississippi Delta in 1923, this story captures the mind and manners of the Fairchilds, a large aristocratic family, self-contained and elusive as the wind. The vagaries of the Fairchilds are keenly observed, and sometimes harshly judged, by nine-year-old Laura McRaven, a Fairchild cousin who takes The Yellow Dog train to the Delta for Dabney Fairchild's wedding. An only child whose mother has just died, Laura is resentful of her boisterous, careless cousins, and desperate for their acceptance. As the hour moves closer and closer to wedding day, Laura arrives at a more subtle understanding of both the Fairchilds and herself.
