Aveline

For thirteen-year-old Aveline Fleur, a child of Alterra's ruling house, life is pretty much perfect. She attends private school, owns a horse, and lives on an enormous estate where she and her best friend Bruno run wild. But when she discovers that her family is involved in a sinister plot to brainwash people who speak out against the regime—and that Bruno and his mother are in danger—Aveline must summon the courage to save herself and her friends before it's too late.
