Here is the fourth collection of stories in the genre of heroic fantasy with elements of Scandinavian mythology from the Mirror series from Denis Tikhiy and Elena Kleshchenko. The book, like the previous parts of the cycle, has a gender concept: for each topic, the reader is offered two texts - male and female. Could you die to save another's life? The hero of one of the stories is ready to go for it... twice. But first he needs to become a man, because now he is a robot... As a reclusive professor, escape from a rogue with the speaking nickname Lipuchka, conceived to kill a scientist and cash in on his great discovery? If there was an alternative version of military service using virtual reality, what would be the way to slope away from it? And what to do, if a blue-haired beauty came home and said that you urgently need to remember who you really are?
