This is a startlingly original piece of science fiction, which is as fascinating in its look at the history of 20th century China as it is with its story of the beginnings of an alien invasion, by a superior technology. Cixin Liu cleverly interweaves the historical backdrop to the contemporary story with that of a virtual reality 'game' designed to win converts to an understanding of what the aliens have done to human society.
Beginning in the 1960s, the story focuses on Ye Wenjie's work at the Red Coast station. A place she thinks is designed to track and destroy imperialist space-craft. Instead, the highest levels of the Chinese government are concerned that attempts to communicate with aliens will initially come from the capitalists, not the puveyors of peace and socialism represented by the Chinese state. Socialist readers may well smile at this, but the denunciation of the deviate socialism of the Soviet Union by the characters in the book certainly evokes certain Maoist political propaganda. Ye Wenjie manages to communicate with an alien society, and despite a warning not too from a dissident alien, she directs the civilisation to Earth.
But faster than light travel is not available, and the aliens know that they could arrive at an Earth with better technology than they have, so they devise a cunning plan to undermine Earth technology. To encourage science to be feared, and scientists themselves to go insane. Its into this world that the character at the centre of the story, a nanotech scientist, Wang Miao is plunged when the united secret services and military forces of the world conspire to try and find out what is happening.
The novel is original, and highly enjoyable. At times some of the characters felt a bit thin, and the dialogue a little wooden. I don't know whether that is the writing, or the difficulties of translating Chinese into English. There are certainly lots of footnotes to explain the history, the translation and cultural differences which I actually found added to the novel. Despite this limitation the story builds up to a satisfying climax and I look forward very much to the follow up volumes.
