The book includes three famous works by Grigory Oster — "School of Horrors", "A book about delicious and healthy food of an ogre" and "Terrible tasks". Everyone knows that it is difficult for children to live in the world: adults — parents and teachers — all the time require them to behave well, not make noise, not jump, do homework and study only for four and five. You should have tried it yourself! That's why these chilling stories about school witches, vampires, cannibals and other evil spirits were born. You never know who is hiding under the guise of peaceful schoolchildren, teachers and even parents!
