The Demon Headmaster by Gillian Cross

4.0

A middle grade adventure about a girl with above-average smarts moving into a foster home with two boys who can't seem to stay out of trouble at their school. She's skeptical at first at their seemingly wild stories about how wicked the headmaster is, but she soon discovers the truth of it. They finally work together to discover what the evil man is up to and then try to come up with a plan to stop his insane plans.
A fun story with equally fun characters and a plot that would keep even reluctant young readers engaged. I'd definitely recommend this one to all sorts of kiddos.
