The hilarious children’s book from No. 1 bestselling author David Walliams.

On a volcanic island, in the middle of shark-infested waters, stands The Cruel School. The lessons are appalling, the school dinners are revolting and the teachers are terrifying – especially the mysterious Science teacher Doctor Doktur.

When Larker is sent to the school, she quickly realises something very odd is going on… something involving Doctor Doktur, a pair of strange spectacles, and a ‘Monsterfication Machine’. And ultimately she finds herself face to face with a real life Megamonster.

There seems to be no escape – but for Larker, nothing is impossible…
