The Three-Body Problem is the first chance for English-speaking readers to experience this multiple award winning phenomenon from China's most beloved science fiction author, Liu Cixin.

Set against the backdrop of China's Cultural Revolution, a secret military project sends signals into space to establish contact with aliens. An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion. The result is a science fiction masterpiece of enormous scope and vision.

Editorial Reviews

From the Publisher

“Remarkable, revelatory and not to be missed.” —Kirkus Reviews, starred review
Library Journal
During China's cultural revolution of the 1960s, a woman who is a political undesirable finds purpose at a secret military base that is sending signals into space to communicate with an alien culture. Years later, a video game called Three Body may hold the key to what those aliens want from Earth, and a physicist gets pulled into a worldwide effort to prepare for their arrival. VERDICT This 2006 Chinese best seller finally gets an English translation from Nebula and Hugo Award winner and author Ken Liu. Along with the unusual setting, the novel includes a lot of discussions of high-level physics (sometimes helpfully couched within the video game), as the aliens come from a world with three suns and the unpredictable motions of the trisolaran system threaten their continued existence. It's not an easy sell to Western readers, but the translator provides helpful footnotes explaining the unfamiliar historical and cultural references. Fans of hard sf likened to the work of Arthur C. Clarke will look forward to the rest of the series. [See Eric Norton's sf/fantasy feature, "A Multiplicity of Realms," LJ 8/14.]

The Madness Years

China, 1967

The Red Union had been attacking the headquarters of the April Twenty-eighth Brigade for two days. Their red flags fluttered restlessly around the brigade building like flames yearning for firewood.

The Red Union commander was anxious, though not because of the defenders he faced. The more than two hundred Red Guards of the April Twenty-eighth Brigade were mere greenhorns compared with the veteran Red Guards of the Red Union, which was formed at the start of the Great Proletarian Cultural Revolution in early 1966. The Red Union had been tempered by the tumultuous experience of revolutionary tours around the country and seeing Chairman Mao in the great rallies in Tiananmen Square.

But the commander was afraid of the dozen or so iron stoves inside the building, filled with explosives and connected to each other by electric detonators. He couldn't see them, but he could feel their presence like iron sensing the pull of a nearby magnet. If a defender flipped the switch, revolutionaries and counter-revolutionaries alike would all die in one giant ball of fire.

And the young Red Guards of the April Twenty-eighth Brigade were indeed capable of such madness. Compared with the weathered men and women of the first generation of Red Guards, the new rebels were a pack of wolves on hot coals, crazier than crazy.

The slender figure of a beautiful young girl emerged at the top of the building, waving the giant red banner of the April Twenty-eighth Brigade. Her appearance was greeted immediately by a cacophony of gunshots. The weapons attacking her were a diverse mix: antiques such as American carbines, Czech-style machine guns, Japanese Type-38 rifles; newer weapons such as standard-issue People's Liberation Army rifles and submachine guns, stolen from the PLA after the publication of the "August Editorial"; and even a few Chinese dadao swords and spears. Together, they formed a condensed version of modern history.

Numerous members of the April Twenty-eighth Brigade had engaged in similar displays before. They'd stand on top of the building, wave a flag, shout slogans through megaphones, and scatter flyers at the attackers below. Every time, the courageous man or woman had been able to retreat safely from the hailstorm of bullets and earn glory for their valor.

The new girl clearly thought she'd be just as lucky. She waved the battle banner as though brandishing her burning youth, trusting that the enemy would be burnt to ashes in the revolutionary flames, imagining that an ideal world would be born tomorrow from the ardor and zeal coursing through her blood.... She was intoxicated by her brilliant, crimson dream until a bullet pierced her chest.

Her fifteen-year-old body was so soft that the bullet hardly slowed down as it passed through it and whistled in the air behind her. The young Red Guard tumbled down along with her flag, her light form descending even more slowly than the piece of red fabric, like a little bird unwilling to leave the sky.

The Red Union warriors shouted in joy. A few rushed to the foot of the building, tore away the battle banner of the April Twenty-eighth Brigade, and seized the slender, lifeless body. They raised their trophy overhead and flaunted it for a while before tossing it toward the top of the metal gate of the compound.

Most of the gate's metal bars, capped with sharp tips, had been pulled down at the beginning of the factional civil wars to be used as spears, but two still remained. As their sharp tips caught the girl, life seemed to return momentarily to her body.

The Red Guards backed up some distance and began to use the impaled body for target practice. For her, the dense storm of bullets was now no different from a gentle rain, as she could no longer feel anything. From time to time, her vinelike arms jerked across her body softly, as though she were flicking off drops of rain.

And then half of her young head was blown away, and only a single, beautiful eye remained to stare at the blue sky of 1967. There was no pain in that gaze, only solidified devotion and yearning.

And yet, compared to some others, she was fortunate. At least she died in the throes of passionately sacrificing herself for an ideal.

* * *

Battles like this one raged across Beijing like a multitude of CPUs working in parallel, their combined output, the Cultural Revolution. A flood of madness drowned the city and seeped into every nook and cranny.

At the edge of the city, on the exercise grounds of Tsinghua University, a mass "struggle session" attended by thousands had been going on for nearly two hours. This was a public rally intended to humiliate and break down the enemies of the revolution through verbal and physical abuse until they confessed to their crimes before the crowd.

As the revolutionaries had splintered into numerous factions, opposing forces everywhere engaged in complex maneuvers and contests. Within the university, intense conflicts erupted between the Red Guards, the Cultural Revolution Working Group, the Workers' Propaganda Team, and the Military Propaganda Team. And each faction divided into new rebel groups from time to time, each based on different backgrounds and agendas, leading to even more ruthless fighting.

But for this mass struggle session, the victims were the reactionary bourgeois academic authorities. These were the enemies of every faction, and they had no choice but to endure cruel attacks from every side.

Compared to other "Monsters and Demons," reactionary academic authorities were special: During the earliest struggle sessions, they had been both arrogant and stubborn. That was also the stage in which they had died in the largest numbers. Over a period of forty days, in Beijing alone, more than seventeen hundred victims of struggle sessions were beaten to death. Many others picked an easier path to avoid the madness: Lao She, Wu Han, Jian Bozan, Fu Lei, Zhao Jiuzhang, Yi Qun, Wen Jie, Hai Mo, and other once-respected intellectuals had all chosen to end their lives.

Those who survived that initial period gradually became numb as the ruthless struggle sessions continued. The protective mental shell helped them avoid total breakdown. They often seemed to be half asleep during the sessions and would only startle awake when someone screamed in their faces to make them mechanically recite their confessions, already repeated countless times.

Then, some of them entered a third stage. The constant, unceasing struggle sessions injected vivid political images into their consciousness like mercury, until their minds, erected upon knowledge and rationality, collapsed under the assault. They began to really believe that they were guilty, to see how they had harmed the great cause of the revolution. They cried, and their repentance was far deeper and more sincere than that of those Monsters and Demons who were not intellectuals.

For the Red Guards, heaping abuse upon victims in those two latter mental stages was utterly boring. Only those Monsters and Demons who were still in the initial stage could give their overstimulated brains the thrill they craved, like the red cape of the matador. But such desirable victims had grown scarce. In Tsinghua there was probably only one left. Because he was so rare, he was reserved for the very end of the struggle session.

Ye Zhetai had survived the Cultural Revolution so far, but he remained in the first mental stage. He refused to repent, to kill himself, or to become numb. When this physics professor walked onto the stage in front of the crowd, his expression clearly said: Let the cross I bear be even heavier.

The Red Guards did indeed have him carry a burden, but it wasn't a cross. Other victims wore tall hats made from bamboo frames, but his was welded from thick steel bars. And the plaque he wore around his neck wasn't wooden, like the others, but an iron door taken from a laboratory oven. His name was written on the door in striking black characters, and two red diagonals were drawn across them in a large X.

Twice the number of Red Guards used for other victims escorted Ye onto the stage: two men and four women. The two young men strode with confidence and purpose, the very image of mature Bolshevik youths. They were both fourth-year students majoring in theoretical physics, and Ye was their professor. The women, really girls, were much younger, second-year students from the junior high school attached to the university. Dressed in military uniforms and equipped with bandoliers, they exuded youthful vigor and surrounded Ye Zhetai like four green flames.

His appearance excited the crowd. The shouting of slogans, which had slackened a bit, now picked up with renewed force and drowned out everything else like a resurgent tide.

After waiting patiently for the noise to subside, one of the male Red Guards turned to the victim. "Ye Zhetai, you are an expert in mechanics. You should see how strong the great unified force you're resisting is. To remain so stubborn will lead only to your death! Today, we will continue the agenda from the last time. There's no need to waste words. Answer the following question without your typical deceit: Between the years of 1962 and 1965, did you not decide on your own to add relativity to the intro physics course?"

"Relativity is part of the fundamental theories of physics," Ye answered. "How can a basic survey course not teach it?"

"You lie!" a female Red Guard by his side shouted. "Einstein is a reactionary academic authority. He would serve any master who dangled money in front of him. He even went to the American Imperialists and helped them build the atom bomb! To develop a revolutionary science, we must overthrow the black banner of capitalism represented by the theory of relativity!"

Ye remained silent. Enduring the pain brought by the heavy iron hat and the iron plaque hanging from his neck, he had no energy to answer questions that were not worth answering. Behind him, one of his students also frowned. The girl who had spoken was the most intelligent of the four female Red Guards, and she was clearly prepared, as she had been seen memorizing the struggle session script before coming onstage.

But against someone like Ye Zhetai, a few slogans like that were insufficient. The Red Guards decided to bring out the new weapon they had prepared against their teacher. One of them waved to someone offstage. Ye's wife, physics professor Shao Lin, stood up from the crowd's front row. She walked onto the stage dressed in an ill-fitting green outfit, clearly intended to imitate the military uniform of the Red Guards. Those who knew her remembered that she had often taught class in an elegant qipao, and her current appearance felt forced and awkward.

"Ye Zhetai!" She was clearly unused to such theater, and though she tried to make her voice louder, the effort magnified the tremors in it. "You didn't think I would stand up and expose you, criticize you? Yes, in the past, I was fooled by you. You covered my eyes with your reactionary view of the world and science! But now I am awake and alert. With the help of the revolutionary youths, I want to stand on the side of the revolution, the side of the people!"

She turned to face the crowd. "Comrades, revolutionary youths, revolutionary faculty and staff, we must clearly understand the reactionary nature of Einstein's theory of relativity. This is most apparent in general relativity: Its static model of the universe negates the dynamic nature of matter. It is anti-dialectical! It treats the universe as limited, which is absolutely a form of reactionary idealism...."

As he listened to his wife's lecture, Ye allowed himself a wry smile. Lin, I fooled you? Indeed, in my heart you've always been a mystery. One time, I praised your genius to your father—he's lucky to have died early and escaped this catastrophe—and he shook his head, telling me that he did not think you would ever achieve much academically. What he said next turned out to be so important to the second half of my life: "Lin Lin is too smart. To work in fundamental theory, one must be stupid."

In later years, I began to understand his words more and more. Lin, you truly are too smart. Even a few years ago, you could feel the political winds shifting in academia and prepared yourself. For example, when you taught, you changed the names of many physical laws and constants: Ohm's law you called resistance law, Maxwell's equations you called electromagnetic equations, Planck's constant you called the quantum constant.... You explained to your students that all scientific accomplishments resulted from the wisdom of the working masses, and those capitalist academic authorities only stole these fruits and put their names on them.

But even so, you couldn't be accepted by the revolutionary mainstream. Look at you now: You're not allowed to wear the red armband of the "revolutionary faculty and staff"; you had to come up here empty-handed, without the status to carry a Little Red Book.... You can't overcome the fault of being born to a prominent family in pre-revolutionary China and of having such famous scholars as parents.

But you actually have more to confess about Einstein than I do. In the winter of 1922, Einstein visited Shanghai. Because your father spoke fluent German, he was asked to accompany Einstein on his tour. You told me many times that your father went into physics because of Einstein's encouragement, and you chose physics because of your father's influence. So, in a way, Einstein can be said to have indirectly been your teacher. And you once felt so proud and lucky to have such a connection.

Later, I found out that your father had told you a white lie. He and Einstein had only one very brief conversation. The morning of November 13, 1922, he accompanied Einstein on a walk along Nanjing Road. Others who went on the walk included Yu Youren, president of Shanghai University, and Cao Gubing, general manager of the newspaper Ta Kung Pao. When they passed a maintenance site in the road bed, Einstein stopped next to a worker who was smashing stones and silently observed this boy with torn clothes and dirty face and hands. He asked your father how much the boy earned each day. After asking the boy, he told Einstein: five cents.

This was the only time he spoke with the great scientist who changed the world. There was no discussion of physics, of relativity, only cold, harsh reality. According to your father, Einstein stood there for a long time after hearing the answer, watching the boy's mechanical movements, not even bothering to smoke his pipe as the embers went out. After your father recounted this memory to me, he sighed and said, "In China, any idea that dared to take flight would only crash back to the ground. The gravity of reality is too strong."

"Lower your head!" one of the male Red Guards shouted. This may actually have been a gesture of mercy from his former student. All victims being struggled against were supposed to lower their heads. If Ye did lower his head, the tall, heavy iron hat would fall off, and if he kept his head lowered, there would be no reason to put it back on him. But Ye refused and held his head high, supporting the heavy weight with his thin neck.

"Lower your head, you stubborn reactionary!" One of the girl Red Guards took off her belt and swung it at Ye. The copper belt buckle struck his forehead and left a clear impression that was quickly blurred by oozing blood. He swayed unsteadily for a few moments, then stood straight and firm again.

One of the male Red Guards said, "When you taught quantum mechanics, you also mixed in many reactionary ideas." Then he nodded at Shao Lin, indicating that she should continue.

Shao was happy to oblige. She had to keep on talking, otherwise her fragile mind, already hanging on only by a thin thread, would collapse completely. "Ye Zhetai, you cannot deny this charge! You have often lectured students on the reactionary Copenhagen interpretation of quantum mechanics."

"It is, after all, the explanation recognized to be most in line with experimental results." His tone, so calm and collected, surprised and frightened Shao Lin.

Compared to other homogeneous western works, the Earthmans might not facing the cruellest circumstance(at least not in first book of the series) but it's certanly complicated and dramatic enough to make characters and readers squeeze their hearts waiting for what happened next. No need to be confused by those chinese names, they are the only thing that have nothing to do with all those grand narratives that full of imaginative metaphors. Sit tight and enjoy it , I myself doesn't get the point of the plot metaphor on the first pass, but it surely is a good story enough for me to read it again and again.

I don't consider myself a fan of science fiction as much as a fan of good books in general and this is definitely a good book for any one. As a busy mom of two toddlers with zero time to read I'm glad that I skipped a couple of hours of sleep each night to read The Three Body Problem by Cixin Liu: not only was I reminded of the shear enjoyment of reading but I chose a worthy book to read (I originally discovered Three Body via a positive Wall Street Journal review/article that I read in my doctor's waiting room). Non-science fiction adherents will appreciate that Three Body isn't just about science and technology "mumbo-jumbo" (but there is still a lot of that). It is also an exploration as to how extreme set-backs (whether it be victimization by the Chinese Cultural Revolution or disappointment with humanity's stewardship of the Earth) could affect individuals and how it may color their view of humankind. The book also explores xenophobia and immigration issues indirectly (i.e., Should we help a people who are in danger of destruction - to the point of disappearing from existence - even if their leadership can't "play nice"?). I especially enjoyed the lesson that even the person one thinks is the most useless/crazy/uneducated/annoying/etc. can have a winning idea (see Chapter 31 - Operation Guzheng). My only bad point about this book (and I'm really only nit-picking here) is that this book uses more than a few literary devices to tell its story: third-person omnipotent; memos exchanged between government officials; interrogation transcripts; flash-backs; etc. The timeline is somewhat non-linear. The author makes it work until the near the end of the book with one of the last flash-backs/interrogation transcripts. I got a little bored at this point because I felt this part was unnecessary. I don't believe that I'm giving anything away by saying that I was paying attention throughout the book and knew that one of the protagonists was indeed responsible for some crimes. I suppose the author felt he had to include this chapter in case readers needed the extra "hand holding". In summary, I highly recommend Three Body But don't just take my word for it: this website (and others) are offering a free preview of the first two chapters at the time of this writing. I plan to purchase the next two books in the trilogy as soon as they are released in the U.S. I've read on-line reviews from Chinese language readers that the sequels are even better. Can't wait.

I'd like to give this book 2.5 stars but that choice is not available. The translator does a good job of translating the book, I think. I'm not a native Chinese speaker so this statement is made w/ some degree of ignorance. The book itself shines for being hardcore sci-fi with what is most of the time a very strict adherence to real science and physics. This is also the books downfall in many ways as long portions are spent explaining science to drive the plot. If Christopher Nolan movies make you crazy, this book is not for you. The author delves deeply into dimensional physics and a math/physics problem about predicting the behavior of a planet orbiting three suns. The story also uses a virtual realty video game to drive the plot. The virtual realty video game storyline became contrived at times. Liu relied on it heavily to drive the plot. Since its a VR game anything can happen, therefore, the plot changes from within the VR game felt contrived. Liu feeds the science portions of his book rich and fatty portions of his creativity and drive. Chinese history and politics also received some of the most sophisticated and subtle treatments. Plot changes and the storyline were given meager consideration and the reader suffers. I'm not sure if its the Chinese style or something lost in translation but big portions of the book are doled out to the reader in this fashion: [ This happened. Then that happened. Then that happened. Then this happened. Then this character did this. Then that character did that. This character can do this by the way. (To drive the plot goals) So then this happened.] The science, for the most part, makes the story NOT incredulous but the court stenographer writing style makes it read like a plot summary or a writer's notes. One early part of the book shows Chinese government documents about the desire to contact alien life via radio transmissions, this comes off very well and plausible. Later on in the book, actual alien communications are rife with human constructs like bunkers for the president, multi-tasking computers and overworked/underpaid government employees. When Liu delves into dimensional physics and the aliens attempt to contact/reach earth their technology and limitations due to physics sound very believable. By the end of the story the aliens technology is basically pure 'magic' or unobtanium' and can do anything (since it will drive the plot) and the reader is left feeling cheated again. The Chinese perspective and writing style will be refreshing for American readers. The lazy (and then this happened) plot movement will leave many readers feeling unfulfilled. - Moogleydog

Really an exceptional book. There doesn't really seem to be a clear main character in the book - it seems to focus on a scope larger than character development - so no need to spend too much time on the confusing Chinese names.  Can't wait for the sequels.

Good summary of Chinese politics that could not have been written a few years ago. The science fiction is interesting and sometimes hard to follow. The few footnotes are useful to explain the times. A rare few chapters about the aliens side of the events. I can't wait for the two sequels.

As an expat living in China the opportunity to read a best selling popular fiction novel translated into English was worth $13 however reading the story is priceless. The story by itself is a unique first contact story however it is a first contact story from a perspective that is alien to most westerners. Our cultural experiences have a lot to do with how we might react to new ideas. However I worry about saying too much... After the mystery in this book is what you are reading it for. But I'll tell you this the book starts during the cultural revolution and in 19 eBook pages on the nook smart touch the author kills two people and you as the reader will care about both lives. That is impressive writing. One more thing READ THE TRANSLATORS notes very useful

The book is very well written and gets you interested immediately. Then it moves along at a good clip, an easy read for someone who has a little knowledge of physics.

I don't usually read science fiction but thought I'd give this book a try. Enjoyed it, even though it's heavy on the scientific aspects. It was hard warming up to the characters. Look forward to books two and three.

She ran aimlessly through the Dark Foods, stumbling. She had to exscape, but the Darkness would not let her leave. Not without a fight.
