In the year 2312, humanity has stretched its domain across the solar system, transforming inhospitable landscapes into marvels of human ingenuity and resilience. On Mercury, in the city of Terminator, an astonishing feat of engineering orbits perilously close to the sun. Here, Swan Er Hong, a designer of worlds and habitats in space, is thrust into a mystery that begins with a sudden, unanticipated death. This event is merely the harbinger of a series of actions that will catapult Swan from the inner circles of solar system politics and intrigue into a sprawling adventure that questions the very fabric of human evolution and our place among the stars. As Swan journeys from the sun-scorched Mercury to the plush terrains of Venus, from the icy rings of Saturn to the lush, life-filled spaceships ferrying the hopes and dreams of humanity, she uncovers a conspiracy that could spell the end of humanity's vast empire in space. With each revelation, the future of 2312 becomes increasingly uncertain, teetering on the brink of unimaginable change. Kim Stanley Robinson's masterpiece is a vivid, compelling exploration of what it means to be human in a universe of our own making, asking profound questions about heritage, destiny, and the complex relationship between nature and technology.
