The end of the world is approaching Moominvalley! Somewhere far away in the pitch-black Universe, a star with a flaming tail is moving - a comet - which is about to fall to Earth. And then it is unknown what awaits all earthly inhabitants. Moomintroll and Sniff were told about this by their new friend Snufkin, whom they met on the way to the observatory (they went there to find out if the Universe was really so black, and it was a very dangerous journey!). And scientists at the observatory even named the day and hour when the comet will arrive. You can’t hesitate - you need to get home urgently. After all, mom and dad will certainly figure out how to save the world! The book you are holding in your hands is a real event. For the first time in many years, the entire series about the Moomins has been re-translated into Russian! Those who are already familiar with the inhabitants of Moominvalley will be curious to take a fresh look at their adventures. And those who are about to meet the fairy-tale world of Tove Jansson for the first time can only be envied in a good way!
