Time is running out for humanity in The Dark Forest, the stunning sequel to Cixin Liu's award-winning and bestselling masterpiece, The Three-Body Problem. Earth is still reeling from the revelation of a coming alien invasion. The aliens' human collaborators may have been defeated, but the presence of the sophons, the subatomic particles that allow Trisolaris instant access to all human information, means that Earth's defense plans are totally exposed to the enemy. Only the human mind remains a secret. This is the motivation for the Wallfacer Project, a daring plan that grants four people enormous resources to design secret strategies, hidden through deceit and misdirection from Earth and Trisolaris alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer and sociologist, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead. The Dark Forest continues Cixin Liu's ground-breaking saga of incredible scope and vision.
