The book is a continuation of the story “Replacement”, published on the Internet. This was in the middle of the last century. In a parallel world, a relaxed civilization, having forgotten about wars or various kinds of restrictions, seemed eternal. However, the long-standing curse of previous eras of history has awakened again - the mutual hostility of empires that did not divide the zones of influence on the planet. Characters raised in the cultures of two civilizations do not understand what to do when the authorities begin to quarrel. The main character worries about his son, who is being mobilized to the front.
