I've read Roll of Thunder, Hear my Cry and it's sequel to my children for homeschool. They are are stories about newly freed slaves that continue to farm the previous slave-owner's land in exchange for a place to live and part of the crop's proceeds (with cheating involved.) The black children have segregated buses and schools, and get all the worn-out hand-me-down, falling apart school books from the white schools. Black children get accused of crimes that privileged white teens commit.
