His novel Nemesis, which critics considered not too successful, Isaac Asimov dedicated "Mark Hearst, my indispensable editor, who, I think, works on my manuscripts more than I do." The book is about an as yet unexplored star hiding behind a dusty cloud halfway from the Sun to Alpha Centauri. The action takes place in the year 2236 and the Earth is threatened with death. Scientists from near-Earth orbit are building a starship capable of developing the speed of light This ship and opens in the Nemesis system the planet Eritro, fully adapted to human life, but adversely affecting his brain. Only the daughter of the main character Marlena does not affect the “erythronic plague”, because, as it later turned out, she had some telepathic abilities since childhood. It was the girl who was able to understand the fact that the action of Eritro on a person ultimately brings good. And Marlena becomes an “interpreter” and a representative of Eritro’s Mind, because she was not like everyone else. She was able to “read” people’s gestures and therefore always knew what a person had in mind. Nemesis had to pass through the solar system in five thousand years and then the Earth would die. And Eritro suggested a way out of this situation.
