Megamonster by David Walliams

Megamonster is an action-packed page-turning adventure, set on an island in the middle of shark-infested waters – where the Cruel School stands on top of a dormant volcano. 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 for pulling a prank, 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 .
