The Demon Headmaster - Tapa blanda

a rattling good yarn (TLS )

It's exciting stuff that will have you on the edge of your seat until the very end (Primary Times )

Dinah moves in with the Hunter family and starts going to the same school as her foster-brothers Lloyd and harvey. It's not easy, as they seem to hate her, and school is really strange. Pupils suddenly talk like robots and do weird things - even Dinah finds herself acting oddly. She's sure the headmaster has some kind of power over them, and is determined to find out more. But the Demon Headmaster is equally determined to stop her. BLGillian Cross has won the Carnegie Medal, the Whitbread Children's Novel Award, and the Smarties Prize, and is a highly-acclaimed author.
