Here, on Procyon, the unthinkable happened - the creators swapped places with their creations. The carriers of artificial intelligence, using the technology created by the Selenites who perished in the ray of time, recreated... people. Deprived of memory of a past that they, in general, did not have, they turned into experimental material for androids. The best of the generation created, Jan Kowalski and Marie Lerman, taking mortal risks, are trying to find the answer to the eternal questions: who are we? where did they come from? Why do we exist? They receive unexpected support from their mortal enemy, Colonel Nagaev - a supermachine and a superman in one body... The book was also published under the title “Procyon.”
