I just finished reading a real sci-fi classic. Solaris by Stanislaw Lem. I read an old Swedish translation, made from the German translation from the Polish original from 1961. There are newer translations, but I haven't had access to them.
Probably because I knew of Tarkovsky's film before the book, I always assumed Lem was a Russian author. Wrong! He was Polish, born in 1921 in Lwow, which is now in Ukraine. He died in 2006.
The story is very original, and while it is over fifty years old, it does not feel dated. Except for one thing. Computers are mentioned, but not used very much. Data is still mainly in books. But it does not take anything away from the story. A good and puzzling read.
Lem was a very productive author, and I'll see if I can find any other of his books in languages I can read.
