A Friendship for Today by Patricia McKissack

There's a lot going on in Rosemary's life, but luckily, this strong-willed, smart girl can handle everything that comes her way. After the 1954 Supreme Court ruling on desegregation, Rosemary' all-black school is closed, and she has to attend a school where she is the only black student. She has to face the unkindness of some of the students, in addition to dealing with her parents' faltering marriage, and her best friend being stricken with polio. The development of an unexpected friendship helps her deal with the difficulties in her life. Review by Joyce Levine.
