I read the book as a teen in 1998; it was about a boy (maybe 10 years old) raised on a farm, parents disappeared one day, and the boy continued to tend the farm in their absence. One day he was sprayed by a skunk; he couldn’t smell himself for some reason. He tried to clean up the skunk smell best he could, but as he boarded the bus the school, he could tell he still smelt like skunk based on the looks of the other kids. He exited the bus to return home and he never returned to school. The story goes on to tell his journey of raising the farm without his parents. I believe his parents returned years later.
This sounds familiar, but maybe the main character was a girl? The skunk and bus part do sound very familiar.
I remember reading this in middle school, but I don’t remember the title.
