Summary

Set three centuries from now, this novel follows Swan Er Hong across a solar system that humanity has settled from the sweltering cities of Mercury to terraformed asteroids and the moons of the outer planets. Robinson weaves a mystery about a possible attack on Mercury together with a sweeping meditation on artificial intelligence, gender, climate, and how a divided humanity might endure. The book stands as one of his most ambitious portraits of a future that is both utopian and deeply troubled.
