THREE BODY THE THIRD

Deaths End transforms physics into a nightmare hellscape of horror and loss. Also， theres a love story.

面对宇宙的真相，一切都會逝去，只有死神永生

For a brief recap of the trilogy， Three-Body Problem asked， “Does humanity deserve its place in the universe？” The second， Dark Forest， asked， “Can humanity earn its chance to survive？” In Deaths End the question is somewhat simpler： “Would you sell your mother to a whorehouse？”

If you need to be told that even a simple review of the third in the Three-Body trilogy has spoilers， then you clearly dont know Liu Cixin. Put simply， the man has never seen a well-manicured， rational plot that he didnt want to kick down a flight of stairs， kind of like a George R.R. Martin for planets. So， if youve read this far into the review without having read the Hugo Award-winning Three-Body Problem and Dark Forest， you are a base knave， a failed Wallfacer， and a prick-eared cur of Trisolaris.

Translated by Ken Liu， readers cant just jump in the deep end of Deaths End. Youll need to know about Trisolaris politics， Dark Forest theory， and sophons to understand even a whiff of this novel. Return readers are warned， however， not to expect any fairy tale endings—though this installment does contain actual fairy tales （its complicated）.

Deaths End builds on the Deterrence Era established by Dark Forest. For those hoping this work will finally concentrate on the unbelievably powerful， technologically superior， psychologically advanced horde of brutal alien refugees barreling toward the Earth at one percent of light speed， forget about it. Humanity has bigger problems.

No philosophical meandering， no wishy-washy terrorist groups， no escapism—this time humankind learns or it burns. Its a hard slog through murky waters， and readers wont take long to learn that this novel isnt about narrative tricks. Its about decisions that hurt.

The character in the middle of this maelstrom of bad choices is Cheng Xin who comes out of college at the end of the Crisis Era， during which humanity puts all of its resources into staving off the Trisolaran invasion of Earth. She， a low-level analyst in an important military project， quickly rises through the ranks of the international team of egg-heads due to her practical mind and ownership of a star （its complicated）.

Deaths End is the only book in the trilogy to feature a female lead， and her sex—or， rather， the perception of her sex as a delicate symbol of morality and compromise—plays a major part in the decisions that shape the novel. Shes hardworking， kind， thoughtful， and considerate， but hardly one of Lius stronger characters. Perhaps she only makes sense when considering her foil， Thomas Wade， a hateful， bellicose， headstrong， manipulative monster of a man.

The technology of cryogenics plays an even more important roleDeaths Endthan inDark Forest， allowing the reader to traverse centuries with the turn of a page. With the Doomsday Battle over and Dark Forest theory as an effective deterrent， humanity seems to turn back in on itself， concerned with its own internal politics， eschewing the brutalities of life in the universe， obsessed not with the stars but with the Trisolarians. This inward gaze makes humanity weak—though perhaps “delicate” is a better word.

After centuries of one-sided warfare， scheming， and suicidal military campaigns， humankind is getting back to the business of equality and gentility， and what could be wrong with that？ Well， in a universe ruled by Natural Selection， everything is wrong with that. Complacency is a strong theme in Lius works. From the Three-Body trilogy to his short works， whenever Liu Cixin sees a fictional society sitting on its laurels， you can be sure he is going to step on its neck. Deaths End is no different.

Cheng Xin rises in the world in no small part because of her middle-of-the-road status as a Crisis Era woman. In the Deterrence Era， masculinity exists only in the cryogenically revived men from centuries past. This new delicate society—without going into the specifics of Dark Forest theory—need someone tough enough to do whats necessary but not go off half-cocked. Cheng Xin was the natural choice： a woman but a woman from an age when men were men （its complicated）. From then on， the novel takes on the tone of a morality play with Cheng Xin at the epicenter， but the question of ethics or survival is pretty simple. Again， “Would you sell your mother to a whorehouse？”

Speaking of our pitiless， spiteful universe， theres a Band-Aid that needs to be ripped off： world-building has never been Lius strong suit. This， however， isnt necessarily a bad thing; claustrophobia plays its part in Lius storytelling， so adopting a holistically descriptive style would rather defeat the purpose. If he says a characters in a bunker， you get the gist. If he says a planet has blue trees， fine， get on with it. With a brutal touch of perturbing scientific speculation and a story that spans galaxies and centuries， something as simple as a planet （or genocide） seems to go by in an instant. But， somehow， readers are able to walk away still satisfied that they experienced it—even if the book does sometimes read more like a history book sidebar than a science fiction novel.

The scale of the story， like many of Lius works， is impressive. When we last left humanity inDark Forest， the human race had two long-term space missions， colonies throughout the solar system， and a military force that spanned from the Sun to the Oort Cloud （until it exploded）. The Crisis Era set in motion a complete dedication to Earths survival （minus the Great Ravine）， and the overall attitude is perhaps best summed up by the evil/valiant leader Thomas Wade： “We can throw resources at this problem until the laws of physics bend.”Deaths Endbuilds on an empire， but with an eye to contented survival rather than expansion.

At first glance， the vicious consistency of Thomas Wade always feels like the answer： shoot first， ask questions later， and bugger the cost. But， this is only in appearance because Cheng Xin is actually making all the decisions rather than sniping （literally） from the sidelines. In truth， Thomas Wades view of the universe and the price that needs to be paid has its very own flaw， perhaps put best by the character 白 Ice （its complicated）： “Weakness and ignorance are not barriers to survival， but arrogance is.” Cheng Xin may appear superficially innocent， but Thomas Wade is arrogant to the core.

While Deaths End doesnt really mention the fan favorite， Da Shi， Luo Ji returns in force as the grizzled， centuries-old protector of the planet， a man out of time—also， eventually， out of width， breadth， and a few other dimensions as well. Luos Dark Forest theory implicitly stated what was explicitly stated in Deaths End by an unnamed character/god-like creature chucking weapons at random low-entropy entities （its complicated）： “In the cosmos， no matter how fast you are， someone will be faster.” Luo lives long enough to see his theory become irrelevant. No matter how well you hide， no matter how well you fight， something is coming that cant be beat.

In between all this genocide and fatalism there is a love story—albeit a love story involving a cancer victim/flying brain/clone （its complicated）. The nature of the love story in the novel shouldnt surprise Liu Cixin fans considering Dark Forest featured an entirely fictional soul mate and a lovers tiff in “Curse 49” nearly destroyed all life on Earth. Still， Deaths End manages， as planets are swatted from the cosmos like flies， to make the strained relationship between two people seem important.

Like Clarke and Asimov before him， most readers are wowed by the scale of Lius storytelling， but an oft-omitted praise of his work is the perspective. Edwin AbbotsFlatlandfeatures creatures on a two-dimensional plane discovering a third， and thats very much how it feels to readDeaths End. Fully-formed worlds are neatly laid out for the readers inspection， and the reader feels as though they can speculate on the nature of the plot point set before them. But its not a plot point; its a puzzle piece.

Usually book reviews end with a recommendation of the book， but readers of the first two works will likely be chomping at the bit to get their hands on this final installment. In fans minds， this final work has a lot of area to cover and more than a few questions to answer， so expectations are extremely high. Readers should beware that this book， more than the previous two， challenges the reader to follow Liu Cixin down some very dark paths. So， before readers pick up this final installment to have one of the greatest modern sci-fi masterpieces end forever， they need to ask themselves： “Would you sell your mother to a whorehouse？”
