The Dark Forest by Cixin Liu (Tor)

In his sequel to The Three-Body Problem, Cixin Liu steps out into a whole other world. The Earth is aware that its Doomsday is approaching and inevitable. Trisolaris has covered the planet with a shield of protons that receive and transmit every word that is spoken beneath its envelope of surveillance. Some humans who have the means are considering Escapism, a flight to safe planets, while others choose to undergo hibernation, planning to revive themselves when the Doomsday battle takes place. 

The woman who set this disaster into motion is preparing to die but first she finds an undistinguished academic, Luo Ji, and gives him two axioms that hold the secret of cosmic sociology, but only under the right conditions. Burdened with secrets that might save humanity but which he has no idea of how to use. Luo Ji becomes the most wanted man on Earth and is chosen as one of the men whose brains might forestall Doomsday.

In a transmission to an ally on Earth, Trisolaris reveals a fatal flaw and discovers a human advantage. Trisolarans communicate through thought alone and every thought they have is on visible display. They live in a society without hidden plans, lies, or subterfuge, and initially regard human speech as a biological weakness. Quickly they begin to understand that the human mind is something to fear and humans realize that duplicity is their key to survival. They assemble a group of intellectuals who will develop defense systems in silence, with alternate untruths being sent to Trisolaris in spoken words. The Wallfacers, as they are called, all succumb to the Trisolaris allies called Wallbreakers, all except for Luo Ji.

His plans are all self-serving and hedonistic, allowing him an earthly paradise shared only with the woman he loves. Trisolaris decides he’s ridiculous, worthy only of their extermination. When they infect him with a genetic weapon, a flu that will kill only him,  his doctors put him into hibernation, hoping when he revives in another century there will be a cure for his illness.

But Luo Ji not only carries a fatal virus, he has discovered the secret of the axioms given to him by Ye Wenjie. Can he use them to avert Doomsday?

Once again Cixin Liu has taken a cliched plot and enriched it with prophetic details,  puzzling science, and unexpected swerves. The Dark Forest is more opaque and difficult than its predecessor. Although the story rushes into new arenas, they seem to be dead ends, fascinating but unconnected to the general plot. Even when the ending seems to bring a conclusion, there are too many undecided fates for this to be satisfying--and far too many unanswered questions.

The perennial problem of constructing the middle of an adventure in a way that makes readers want to move on to the next installment is made murkier than usual because of a change in translators. Ken Liu provided quantities of footnotes that helped readers understand The Three-Body Problem and gave its characters ample dialogue to define and sharpen their different personalities. Translator Joel Martinsen has chosen to offer very little of either, evoking suspicion that he understood little of what he put into English and chose simply to translate The Dark Forest word by word. When the universe is at last revealed to be the dark forest, there will be many readers who have no idea of what this means. 

Fortunately the concluding volume of what has been named the Earth’s Past trilogy is back in the capable and brilliant hands of Ken Liu, the perfect choice to  clarify the complexities of Cixin Liu’s enigmatic genius. Don’t stop reading--help is on the way!~Janet Brown
