From the million-copy bestselling author of THE PARENT AGENCY and BIRTHDAY BOY comes a wildly entertaining wish-fulfilment adventure that asks the question: what would happen if the strictest head teacher swapped bodies with the naughtiest kid in school?

Strictest head ÷ naughtiest boy = chaos.

Bracket Wood is about to be visited by the school inspectors. But there’s one big problem: Ryan Ward.

The maestro of practical jokes, Ryan has played so many tricks that in the end the Head Teacher just walks out. And then the new Head Teacher, Mr Carter, arrives. A man so strict even the teachers are scared of him. So imagine his surprise – and Ryan’s – when they swap bodies.

Now Ryan is Head Teacher – and his mortal enemy is one of his pupils. It’s every naughty kid’s dream!

But soon Bracket Wood School is in a total mess – and only its worst ever pupil can fix it?
