The Eye of the Heron chronicles the inhabitants of the planet Victoria, originally a prison colony of Earth. However, 'The People of Peace,' who led a non-violent movement against the great wars of Earth, were also sent to the planet be the government of a great nation. When the novel begins, the people of the prison colony enjoy great comforts in town, disdaining the People of Peace, who do their farming.
Those who live outside the city grow tired of this poor exchange, and want to go found a new city, with no oppression. The novel explores the struggle to do this, as the non-violent people question their own ideals.
This book has beautiful moments, and the characters are well-conceived. However, it lacks the depth of some of Le Guin's other novels like The Dispossesd and The Left Hand of Darkness. It is an enjoyable read, but in the end it is lighthearted rather than than deep and pondering.
