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.
