Here's a hell of a paragraph:

Yesterday afternoon the six-o'clock bus ran over Miss Bobbit. I'm not sure what there is to be said about it; after all, she was only ten years old, still I know no one of us in this town will forget her. For one thing, nothing she ever did was ordinary, not from the first time that we saw her, and that was a year ago. Miss Bobbit and her mother, they arrived on the same six-o'clock bus, the one that comes through from Mobile. It happened to be my cousin Billy Bob's birthday, and so most of the children in town were here at our house. We were sprawled on the front porch having tutti-frutti and devil cake when the bus stormed around Deadman's Curve. It was the summer that never rained; rusted dryness coated everything; sometimes when a car passed on the road, raised dust would stand in the air an hour or more. Aunt El said if they didn't pave the highway soon she was going to move down to the seacoast; but she'd said that for such a long time. Anyway, we were sitting on the porch, tutti-frutti melting on our plates, when suddenly, just as we were wishing that something would happen, something did; for out of the red road dust appeared Miss Bobbit. A wiry little girl in a starched, lemon-colored party dress, she sassed along with a grownup mince, one hand on her hip, the other supporting a spinsterish umbrella. Her mother, lugging two cardboard valises and a wind-up victrola, trailed in the background. She was a gaunt shaggy woman with silent eyes and a hungry smile.

Truman Capote's 'Children on their Birthdays'?

Capote would be my guess, no idea of the work.

John Irving perhaps?

Carmen is correct!
