My niece absolutely loves this series and we enjoyed reading this one together! She says it is "really funny and makes her laugh" and I can confirm she did chuckle her way through it.

'Body swap' theme is hardly original but it's entertainingly done with plenty of silly japes & toilet humour. Great appeal for Walliams fans, it should be popular.

An easy read from the MG section. Kids who loved Chris O’Dowd’s Moone Boy will feel right at home with this book.

Another Baddiel 'what if'.... what if you could be headteacher of your school?

A body swap story between the school prankster and the new headteacher brought in to stop the school from getting closed down (by OFFHEAD). Ryan has pulled some pranks in his time, but when he somehow swaps bodies with the strict Mr Carter, it's like all his Christmases have come at once - what CAN'T he do?! Imagine: school dinners filled with sweets! Teachers having to become pupils while they take the classes instead!

But the school is about to have the inspectors visit - does he really want his school to close?

This book is a quicker read than Baddiel's others, the story takes off straightaway, with lots of pranks and silly humour (Mr Bummington for Mr Barrington, talk about "how weird it was going for a wee" as his headteacher). Saying that, the in-jokes are good if you're familiar with the other Baddiel titles - the twins from The Parent Controller attend this school. The school tortoises featured in AniMalcolm. There's even a joke about David Walliams and Baddiel's own 'Football's Coming Home' hit song:

(to be sung) "You are off the chart! Now it's time to get rid! Thirty years of school. Never seen a worse kid!"

The story goes rather as you expect, with the body swap affecting the points of view and empathy of both, with a rather stereotyped 'enemy' in the posh school (the OBE-honoured Head and snooty pupils).

There are a couple of genuinely moving moments, and the plot is entertaining enough, but I don't think this is Baddiel's strongest children's novel.

Saying that, I'm sure any child reading this will LOVE the idea of another child taking over the school. And with themes of friendship and teamwork key to it all, it's good at its heart.

Could be read solo by a competent 9 year old. Listeners will be interested at around ages 7-12.
