The Left Hand of Darkness by Ursula K. Le Guin

There is neither source nor end, for all things are in the Center of Time. As all the stars may be reflected in a round raindrop falling in the night: so too do all the stars reflect the raindrop. There is neither darkness nor death, for all things are, in the Light of the Moment, and their end and their beginning are one. ~ Ursula K. Le Guin

The Left Hand of Darkness written by Ursula K. Le Guin won both the Nebula and the Hugo awards.
