The third title in this series about a boy and his magical diary, perfect for fans of Jeremy Strong, }Captain Underpants{ and }Tom Gates{.
Fin is in Big Trouble.
He's upset Mrs Johnson and now he's not going on the school trip.
It's time to use the diary again - if he can just tweak what happened today, he'll be on his way to fame, fortune and fearlessness once again.
