What is a short summary of the story, Winter's King, from the collection, The Wind’s Twelve Quarters?

In the story, Winter's King, the young King Argaven of Karhide on Gethen is kidnaped, drugged, and brainwashed so that she (the Gethenians are all androgynes) will, subconsciously, rule the country in a way so as to favor the fraction who kidnaped her. She escapes from this plot by traveling to another planet of the Hainish Ekumen, where her mind is restored. After an education as a diplomat of the Ekumen, she returns to Gethen. Her heir—an infant when she left, but now old due to Argaven's relativistic journey—is an incompetent ruler. So, backed by both the Ekumen and the Karhidish people, King Argaven resumes her reign.
