“Where am I? What’s wrong with me?” It won’t be long before FSB captain and operations department officer Artem Vishnevsky gets an answer to these and other questions. He will be convinced of one thing very soon: the place in which he finds himself is not at all similar to the world he is familiar with, but it looks a lot like a bad dream. This is the distant future of the Earth after a terrible galactic war. The habitat of humanity in the solar system was the Disc, a giant spaceship that managed to save the Earth from complete destruction. Humanity populated the entire Galaxy, but mutations and mixed marriages with various intelligent races greatly changed the appearance of people... And everything would have been fine if, along with Artyom, his sworn enemy, the Arab terrorist Mehmed Katy, had not entered the future. Now Mehmed's goal is to find the enemy and take revenge.
