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… Product Information: • ISBN: 9780008487591 • Author: David Walliams, Tony Ross • Publisher: HarperCollinsChildren\'sBooks • Format: Hardback • Pages: 384 • Dimensions: 22.2 x 14.1 x 3.3 cm
