Five hundred years since its first publication, Thomas More's Utopia remains astonishingly radical and provocative. More imagines an island nation where thousands live in peace and harmony, men and women are both educated, and property is communal. In a text hovering between fantasy, satire, blueprint and game, More explores the theories and realities behind war, political conflicts, social tensions and redistribution, and imagines the day-to-day lives of a citizenry living free from fear, oppression, violence and suffering.

But there has always been a shadow at the heart of Utopia. If this is a depiction of the perfect state, why, as well as wonder, does it provoke a growing unease?

In this quincentenary edition, published in conjunction with Somerset House, More's text is introduced by multi-award-winning author China Mi�ville and accompanied by four essays from Ursula K. Le Guin, today's most distinguished utopian writer and thinker.
