This is an interesting, often strange and haunting, tale, that has some interesting analyses if mankind (or a man) could change the fabric of reality.

Le Guin writes in a melodious, accessible way and is always a pleasure to read. About halfway through, the steady foundations of the first half begin to rock the boat a little bit, but not enough to detract from the story or the message: essentially we have no right.

A solid book. Worth a read.
