“A boy and Karlsson-on-the-Roof”
is a children's book. It was written by the Swedish author Astrid Lindgren. This book was very popular in the Soviet
Union and now it is popular too. Main
characters are a
boy and Karlsson. Karlsson is a very short man who lives in a small house on the roof of a
building in Stockholm. When Karlsson pushes a button on his
stomach, it starts motor with a propeller on
his back, and he can fly. A boy is the
best friend of Karlsson. He is 7. I like
this book. I like Karlsson because of his
sense of humour, energy, and good nature.
