Is BER-66 a human or a robot? His controllers, known as 'the Mechanism,' tell him he is a living machine, programmed to gather information on the inhabitants of the strange underground world he finds himself in. But as he penetrates its tunnels and locked rooms, encountering mysterious doppelgangers and a petrified city, he comes closer to the truth of his existence. Considered one of the most important Polish science fiction novels of all time, Robot is a haunting philosophical enquiry into the nature of our reality and our place in the universe.
