The new children’s book from No。 1 bestselling author David Walliams – a timeless adventure illustrated by artistic genius， Tony Ross。



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…
