I'm not thoroughly familiar with science fiction as a genre, but I'd imagine this is pretty quintessential hard science fiction. That means that quite a lot of text throughout the novel is devoted to explaining the scientific realities behind the events of the narrative. For example, entire chapters are devoted more or less to detailing the physical minutiae of how messages might be transmitted between Earth and alien civilizations.

In the case of this novel, hard science fiction also means substantially less attention is given to the development of characters and the drama between them. Indeed, I found the book somewhat reminiscent of my experience with Isaac Asimov, where all the important characters are STEM academics and the only interesting thing they could imagine talking about is science in one form or another. So don't expect a very compelling drama from this novel or particularly deep or complex characters. With maybe one exception (the character Ye Wenjie) the stakes of this narrative are all practical, not emotional or relational.

But there is (in my mind) a very clever plot in here. The author does a great job of leveraging a variety of concepts and technologies from various STEM disciplines as plot points and narrative developments, both breakthroughs and setbacks for the protagonists. There's also a fascinating layer of 20th century Chinese history that overlays and informs the narrative. But this is neither a thriller nor a romance, so don't expect some pulse-pounding climax at the book's end that will leave you breathless.

I have a degree in a STEM field (computer science) so I may be biased in this assessment, but I thought the book was pretty readable insofar as the science is presented and detailed. But detractors are not wrong to call the writing in general both dry and wooden. I can't tell if it's a authentic reflection of the original author's personal style or perhaps indicative of Chinese prose generally, but in either case this book's writing is far from poetic.

Bottom line, if people are uncertain that they'll be able to get through this book, the only advice I can offer is this: if & when you find yourself struggling to get through a heavy passage detailing scientific minutiae, not only is the novel not going to "get better" from there, but passages such as those are themselves a great part of why this book's fans love it so much. So pull that ripcord early if you find yourself struggling to enjoy yourself; you'll know if this novel is for you pretty quickly. Even those who do enjoy it might be tempted to line up a romance or other drama-rich novel as a chaser.

SPOILERS THO

The three-body problem in physics states that although it is trivial to model the path of two bodies (e.g. binary stars) revolving around each other, it is currently impossible to create a model that can accurately predict the future positions of three bodies around each other, as minute instabilities add up over time to create a chaotic system. This book postulates that the nearest star to the earth, Alpha Centauri, as a ternary star system, is such a chaotic system; despite its unpredictability, a race of sentient species have evolved to sentience on an immensely inhospitable planet. When they learn of the existence of Earth, and realize it is in a stable solar system with a relatively mild climate, what would such a civilization do?

The book reminds me of Carl Sagan's "Contact" (well, the movie; I haven't read the book) but goes beyond the touchy-feely aspects of Sagan's work. Contact is distinctly American, and therefore, deeply religious; when Arroway finally meets aliens, the interaction is solely a personal one, which occurs without any observable proof that it took place at all. With that experience, Arroway is humanity's messiah, able to spread the message that the promised land is a space paradise of hob-nobbing with other, enlightened spacefaring species — if you have faith. 3BP dispenses with the notion that the space age will be a lovely vacation earned by a well-behaved humanity. I don't know if it's because the author takes a very hard-science approach or it's more of a Chinese cultural influence, but the characters in 3BP don't think of joining the aliens because they believe they're worthy. On the contrary, they invite the (presumably enlightened) aliens to Earth as a corrective measure: we're flawed, we're broken, we need your help, come fix us.

Of course, even that ends up being wildly optimistic, as the aliens don't really care about mentoring humans at all. They just want a planet with an easier difficulty level to live on. The universe is a harsh and unforgiving place, and it turns out that outer space isn't the paradise, Earth is. And the aliens wants it for themselves. So, well, they kind of do the science equivalent of driving down the property values so they can swoop in and buy up all the land at a super low price by the time their moving vans get there. (It'll take about 450 years, at a maximum of 10-percent of the speed of light.)

The book ends there. Not with a proclamation of some glorious, kumbaya future, or even a clear evil to be defeated, just a slowly ticking clock. Earth will be occupied in 450 years by star-hopping alien gentrifiers just trying to find a new backyard in which to raise their alien babies. So what now?
