in the first and last chapters: the first takes place on both the moon and the planet; the last takes place in a spaceship. Anarres (chapters 2, 4, 6, 8, 10, 12) Chapter One begins in the middle of the story. The protagonist Shevek is an Anarresti physicist attempting to develop a General Temporal Theory. The physics of the book, Principles of Simultaneity, describes time as having a much deeper, more complex structure than as it is understood. It incorporates not only mathematics and physics, but also philosophy and ethics. Shevek finds his work blocked by a jealous superior, Sabul, who controls the publication of Anarresti manuscripts. As his theories conflict with the prevailing political philosophy, Shevek believes that his ideas are discordant with Anarresti society. Throughout his time in Abbernay, he runs into old acquaintances from his adolescence and his mother, Rulag. One of his old female acquaintances, Takver, becomes involved with Shevek and the two start a relationship and have their first child together. Shevek's work is further disrupted by his social obligation to perform manual labor during a drought in Anarres's anarchist society. To ensure survival in a harsh environment, the people of Anarres must put the needs of society ahead of their own personal desires, so Shevek performs hard agricultural labor in a dusty desert for four years instead of working on his research. After the drought, he arranges to go to Urras, having won a prestigious award for his work there, to finish and publish his theory with the help of the syndicate he set up to distribute his works. His contact with scholars on Urras and his decision to travel results in political turmoil on Anarres. Shevek is accused of being a traitor by Sabul and threatening the political separation between the two worlds. Believing that his theory will benefit the Anarresti and the wider society, Shevek embarks to Urras. Urras (chapters 1, 3, 5, 7, 9, 11) Shevek's journey to the only spaceport in Anarres is eventful. Having been deemed a traitor by some groups on the planet, Shevek is nearly killed as an angry mob tries to stop him getting on the spaceship to A-Io. Arriving in A-Io, Urras, Shevek is feted. He soon finds himself disgusted with the social, sexual, and political conventions of the hierarchical capitalist society of Urras. His grievances are further explored with the outbreak of war in
