Lizzie and her younger brother Tyler aren't looking forward to returning to Hazelbrook Academy. However, when they arrive, they find everything has changed. And it's not for the better. Every pupil is now perfectly behaved and suddenly everyone seems to have a special talent. Even the teachers are acting strangely. And, if that isn't enough, Lizzie inexplicably finds herself throwing food around the canteen and being accused of vandalising the school. Lizzie is determined to find out what has caused the sudden change in everyone's behaviour but it's hard because no one seems to be able to talk about what's going on. It's almost as if the Hazelbrook students are no longer able to think and act for themselves. Could it, perhaps, be something to do with the mysterious new headmaster?
