Le Guin has analyzed the similarities between men and women and their differences. From there, she imagined what would look like a people or beings could during their life, being female, being male but especially and longer "neutral", what would their society. My opinion is that it might make more credible the desire called weaker sex ... But this is only the decor of the central story of this book is that of two human beings that everything separates different world, a different culture, but who nevertheless find themselves in suffering, trials, united by their humanity . A beautiful tale. this book will not be the last Ursula Le Guin that I will read.
