A. Kalugin’s new novel completes the dilogy about the Labyrinth. The invasion of alien creatures called “mechanics” put an end to earthly civilization. A small group of people manage to escape persecution through the passages of the mysterious Labyrinth. A whim or the will of the Labyrinth throws Kiisk and his companions into the past and gives them a chance to save the Earth. To do this, you “just” need to unravel the mystery of the Labyrinth and destroy the universal empire of mechanics. The exciting plot of the novel will not leave anyone indifferent; the reader, together with the author, explores the Unknown and discusses the foundations of the universe.
