"You want to talk to the ocean when you don't even understand each other?"

On the centenary of Stanisław Lem's birth, we are publishing one of the most successful, most magical, and most influential sci-fi of all time, from which three films have already been made.
Psychologist Kris Kelvin arrives at a space station floating above the surface of a distant celestial body, Solaris. The planet is covered in an ocean of plasma that shows signs of a strange intelligence, but humans have so far tried to make contact with it without success.
The psychologist slowly realizes the secret of the planet's functioning - or at least guesses what danger lurks for the people: the plasma ocean drives the researchers to madness: it unleashes the innermost, hidden demons of their personalities.
