content: This is my favorite Le Guin book. As much a political science book as science fiction.Also one one of the feew utopias written after WW2. The title refers to an anarchist society that lives on the moon who do not have possesion. Far from one sided this book shows the problems of both societies through the eyes of Shevek,an Anarres Physicst. Shevek has problems with both his society because the descendents have lost their political idealism and with Urras' because the greed and corruption of it's captialism . A complex work of thought with no easy to find solutions. And a good introduction to the theories of Anarchism.
