About the book: 2021 / The catastrophe changed the world into “BEFORE” and “AFTER”. Millions of megatons of TNT equivalent came from space. Civilization was dealt a serious blow. The world has not died. But people will always remain people. Hard times release the hidden reserves of a person, society, and humanity. Some direct them towards their own survival, others towards the survival of humanity. And ordinary people, in a calm world, events and things take on a completely different meaning. And if one person got his hands on technology that is ahead of its time, then it depends only on him how it will be used. He can destroy the world, or recreate it from ruins. But he is a man, with his own weaknesses and principles. All events, technologies and characters described are fictitious. Any resemblance to events after 2020 is purely coincidental. Contains obscene language.
