After the invention of a rejuvenation pill, space and resources threaten to become scarce on planet Kadohan. The only way out is the search for a replacement planet. The choice is made for the planet "Earth". Unfortunately, intelligent life already exists there … The novel captures the feeling of alienation from nature resulting from the progressive disappearance of landscape behind wind turbines in the image of mankind being overwhelmed by extraterrestrials: The aliens disguise the landing pillars, which they need for the approach of their spaceships to Earth, as installations for generating wind power.
