T "Ana from the stars" (thats translation in my country, in polish it's "Oblok Magellana").
You say it's called
Anna from the stars? - thas unbelieveable. Originally it is the title of one of the chapters of this book (which, as You said, is indeed titled
Oblok Magellana).
Now, about the book. Well, if You've read
Solaris and
Fiasco, then You may find
Oblok... a little different. Moreover, even dissapointing. That's because
Oblok is an (very) early book. Lem wrote in in the middle fifties, being under large pressure from the Communist Party (which, as You no doubt know, ruled Poland at the moment). The book, therefore, is packed with communinist motives. But aside from that - it is quite good ! I personally like it very much. We've talked about it recently in the Polish section of this forum.
Oblok gives an interesting description of an interstellar voyage (8 years one way...). It describes psychological aspects of being 'trapped in the black, cold space' for years. It also contains first Lem's attempts to describe contact with other civilisation.
So, mind all its failures, but definitely give it a try!
And, more importantly - search for other books. I can not believe that, for example,
Star Diaries (Dzienniki Gwiazdowe)) weren't published in You country
