Half a century after the Doomsday Battle, the Dark Forest Deterrence keeps the Trisolaran invaders at bay. It is an uneasy balance, but the infusion of Trisolaran knowledge has triggered an era of unprecedented prosperity on Earth. With human science advancing and the Trisolarans adopting Earth culture, it seems that the two civilizations can co-exist peacefully as equals without the terrible threat of mutually assured annihilation. But has peace also made humanity complacent? Cheng Xin, an aerospace engineer from the 21st century, awakens from hibernation into this new age. She brings knowledge of a long-forgotten program dating from the start of the Trisolar Crisis, and her presence may fatally upset the delicate balance between two worlds. The universe is a dark and dangerous place, devoid of mercy or sentiment. Will humanity reach for the stars or die in its cradle?

The universe is a forest, patrolled by numberless and nameless predators. In this forest, others are hell, a dire existential threat. Stealth is survival. Any civilisation that reveals its location is prey. Earth has. And the others are on the way. The Trisolarian fleet has left their homeworld and will arrive… in four centuries’ time. But the sophons, their extra-dimensional emissaries, are already here and have infiltrated human society and and de-railed scientific progress. Only the individual human mind remains immune to the sophons. This is the motivation for the Wallfacer Project, a last-ditch defence that grants four individuals almost absolute power 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, is baffled by his new status. All he knows is that he’s the one Wallfacer that Trisolaris wants dead. [This text contains hieroglyphs.]
