This time, with the Trisolarans a few years into their voyage, physicist Ye Wenjie (whose reminiscences drove much of the action in the last book) visits astronomer-turned-sociologist Luo Ji, urging him to develop her ideas on cosmic sociology. Humanity’s lone advantage is that Trisolarans are incapable of lying or dissimulation and so cannot understand deceit or subterfuge. On Earth, the Earth-Trisolaris Organization formed to help the invaders, despite knowing the inevitable outcome.

So, determined to capture Earth and exterminate humanity, the Trisolarans embarked on a 400-year-long interstellar voyage and also sent sophons (enormously sophisticated computers constructed inside the curled-up dimensions of fundamental particles) to spy on humanity and impose an unbreakable block on scientific advance. In the previous book, the inhabitants of Trisolaris, a planet with three suns, discovered that their planet was doomed and that Earth offered a suitable refuge. Second part of an alien-contact trilogy ( The Three-Body Problem, 2014) from China’s most celebrated science-fiction author.
