Detstvo bez knig - eto ne detstvo - B'iurvand A.-M.

In this book you will meet an amazing Swedish writer, who as a child often dressed up as a witch,
to frighten young children, loved to play football, until old age climbed trees and dreamed of skiing.
But the main thing: she is the mother of the red-haired girl Pippi, troublemaker Carlson with a motor behind her back, restless Emil, always falling into trouble, and many, many other similarly wonderful heroes of her stunning books.
Have you guessed who it is?
