Alice-Miranda Takes the Lead: Book 3 by Jacqueline Harvey
Alice-Miranda is thrilled to be back at school, where the girls are preparing a play with the neighbouring boys' school. But it's not all glitter and stage lights: there are rumours of a witch in the woods, and Jacinta and Millie are clashing with a rude new student, Sloane, and her pushy mother, September, who's plotting to steal the fortune she's always dreamed of. It's up to Alice-Miranda to set things right!
