The author of the popular fantasy novel series “Kolovrat” presents a new book. In deep space there exists a civilization that overcame wars and diseases, but a thousand years ago the H virus nearly destroyed the galaxy. Now a planet has been found where this virus still exists. A space scout is sent there to find out whether the inhabitants can be cured—or whether the planet must be destroyed. Earth turns out to be infected, and the scout makes contact with the people of Earth in order to help them fight the threat.
