Bye Bye Binary’s selection for their storefront.

“On Gethen, the icy planet that the first humans named Winter, there are no men or women, only human beings.
Androgynous beings who, under certain circumstances, adopt the characteristics of one sex or the other.
The numerous societies that share Gethen all bear the mark of this sexual indifferentiation.
Will the Envoy from Earth, who is considered a monster by the Gethenians, succeed in making them hear the message of the Ekumen?
This splendid novel won the Hugo award and established Ursula Le Guin as one of the greatest talents in science fiction.”
