Twelve-year-old Joan is sure that she is going to be miserable when her family moves from Connecticut to California. Then she meets a most unusual girl. Sarah prefers to be called "Fox" and lives with her author dad in a rundown house in the middle of the woods. The two girls start writing their own stories together, and when one wins first place in a student contest, they find themselves recruited for a summer writing class taught by the equally unusual Verla Volante. The Wild Girls is about friendship, the power of story, and how coming of age means finding your own answers, rather than simply taking adults on faith.
