The Demon Headmaster...

The book I have been reading is called ' The Demon Headmaster ' by Gillian Cross. It is about a school but no ordinary school. ...When you think about a school, you think about a balanced ratio of fun and learning. But this school is no fun, just plain learning and obeying. It is about a girl called Dinah Glass and her two brothers called Harvey and Lloyd. They fight over what school she should go to but she finally decides on this school.... She realises something is off when she enters the school. Everything is silent and very tidy. When she goes to see the headmaster, he turns around and reveals that he can hypnotize the students to do his bidding...
