Sophie and the New Girl by Nancy N. Rue
Sophie's back with more middle-school adventures! The just-formed film club has brought a new girl into the Flakes' orbit: Phoebe is witty, fun, and an awesome actress, but then the girls discover she harbors a prejudice against one of their own. When this same girl is accused of theft, the Pops-and even some of the Flakes-are only too happy to turn against her. And when Dr. Peter suggests that Sophie has a Christian responsibility to try to understand Phoebe, Sophie's ready to throw up her hands. But then the absolute truth dawns: God wants us to reach out to those who are lost-even if it makes us uncomfortable. Armed with insight, Sophie puts faith into action and gains a friend in the process.
