4.5 stars. Deep, profound, slow moving but a thought provoker. As usual, Le Guin's character work is deft and careful, and the world shines through. A good exposition of anarchism (and archism); idealism and realism; hope and practice. This novel may be a bit talk-y (or preach-y) for some, and it's slow in places with long speeches for exposition - but that content is fantastic. 

Probably would be better reading this in print than audiobook form, as I did, so that the reader could repeat some sections that were particularly deft or careful, and Le Guin writes many of these.
