Fiction is, in essence, the modeling of ideas that cannot be implemented in real life. Thus, I. Nemere in “The Case of Kilyos” tries to understand what traveling into the past can give to ordinary mortals with all their shortcomings. The opportunity, for example, to commit the robbery of the century. Or satisfy your ambition and become president. And since the time police are not asleep, the novel takes on the features of a fantastic detective story. Peter Zsoldos in his “Ultimate Task” decides whether it is possible to layer the personality of an earthly spaceman on the brain of a being from another planet and thus prolong his life. And in “The Return of the Viking” it confronts a person with the need to exist not only on another planet, with other people, but also according to other moral laws.
