OK, first off, if you're looking for SF to read, don't bother with this book, because SF it's not, even though it's by Ursula Le Guin. On the other hand, if you're looking for some beautifully written, well-crafted short stories, you might well stop and read.
ORSINIAN TALES is a collection of "mainstream" short stories set in the imaginary Eastern European country of Orsinia, which take place in various time periods ranging from the pagan Dark Ages to the 17th century to the Cold War. They are by turns grim, joyous, lyrical, wistful, and always fascinating. My one cavil is that the date of each story's setting is placed at the end of the story, so if you're not quite sure of the story's period (the period is not always terribly well defined in the opening of the stories, and it makes a difference--at least to me--if a tale is set in 1905 or 1950) you have to peek ahead. But it's a small quibble with a lovely piece of literature.
