Solaris is a 1961 Polish science fiction novel by Stanisław Lem. The book is about the ultimate inadequacy of communication between human and non-human species, an exploration of man’s anthropomorphic limitations.
One of my all time favorites. The Polish national epic, written by the Nobel Prize winning author of Quo Vadis. The first of a trilogy, published in 4 volumes; impossibly long but mesmerizing. Check out the reviews on Amazon.
