Have you ever thought about what happens in the sky during a thunderstorm? Where do lightning and thunder come from? Do you think this is just a result of clouds colliding? Too boring! It is much more interesting to assume that in the world there are such creatures as wind demons, rumble demons and, of course, lightning demons. It is thanks to them that the thunderstorm appears before us in its usual guise: with wind, thunder and lightning. But what happens if one of these celestials accidentally ends up in the human world? Will he be able to survive in a place that is foreign to him and find his way home? This is what the heroes of the book – the imp Kira and the girl Arika – have to find out. They both end up in trouble. And the only chance for them to be saved is to unite, despite all their differences.
