2033rd year. The planet's criminals are isolated in the Great Zone, and the world has collapsed into a consumer society. An elixir of immortality is secretly being created in the Great Zone. But how do they want to use it? Is there a threat to humanity here? Are people ready to accept immortality - or will the gift explode society? A freelance employee of the mystical Academy of Metasciences will have to reveal the plans of the underworld. But what is it like to live with wolves and not become a wolf yourself? Sinners' Paradise is the third book in the Across the Program series, but it stands on its own. The book may appeal to fans of Arkady and Boris Strugatsky. Contains obscene language.
