The year is 2312. Scientific advances have opened gateways to an extraordinary future. Earth is no longer our only home; new habitats have been created throughout the solar system, on moons, planets and in between. But in 2312, a sequence of events will force humanity to confront our past, present and future. The first event takes place on Mercury, in the city of Terminator, itself a miracle of engineering on an unprecedented scale. For Swan Er Hong, it will change her life. Once a designer of worlds, now Swan will be led into a plot to destroy them. 2312 is a bold vision of humanity's future and a compelling portrait of those individuals who will shape its events.
