Dear friend! You have a fantastic book in your hands. Because everything that happens in my brand new story is truly fantastic! A representative of another civilization ended up on planet Earth and became friends with a girl, Katya. And so it began: chases, adventures, scientific research and big politics with real presidents and billions of dollars. Read this book and you will understand that only children who read the books of the writer Uspensky today will know tomorrow how to make world politics and make contact with extraterrestrial civilizations.
