Book Review | Death's End by Cixin Liu

Half a century after the Doomsday Battle, the uneasy balance of Dark Forest Deterrence keeps the Trisolaran invaders at bay. Earth enjoys unprecedented prosperity due to the infusion of Trisolaran knowledge. With human science advancing and the Trisolarans adopting Earth culture, it seems that the two civilizations can co-exist peacefully as equals without the terrible threat of mutually assured annihilation. But peace has also made humanity complacent.

Cheng Xin, an aerospace engineer from the 21st century, awakens from hiber­nation in this new age. She brings knowledge of a long-forgotten program dating from the start of the Trisolar Crisis, and her presence may upset the delicate balance between two worlds. Will humanity reach for the stars or die in its cradle?

The translation and publication of Cixin Liu's Three-Body books has been a singular highlight of the science fiction scene in recent years. The Hugo Award-winning opening salvo of said saga took in physics, farming, philosophy and first contact, and that was just for starters. The world was wondrous, the science startling, and although the author's choice of "a man named 'humanity'" as that narrative's central character led to a slight lack of life, The Three-Body Problem promised profundity.

A year later, The Dark Forest delivered. Bolstered by "a complex protagonist, an engrossing, high-stakes story and a truly transcendent setting, The Dark Forest [was] by every measure a better book" than The Three-Body Problem. Not only did it account for its predecessor's every oversight, it also embiggened the Remembrance of Earth's Past trilogy brilliantly and explored a series of ideas that astonished even seasoned science fiction readers.

But "no banquet was eternal. Everything had an end. Everything." (p.27) And when something you care about does approach that point, all you can do is hope it ends well.

Death's End does.

Book Review | The Dark Forest by Cixin Liu

The universe is a forest, patrolled by numberless and nameless predators. In this forest, others are hell, a dire existential threat. Stealth is survival. Any civilisation that reveals its location is prey.

Earth has. And the others are on the way.

The Trisolarian fleet has left their homeworld and will arrive... in four centuries' time. But the sophons, their extra-dimensional emissaries, are already here and have infiltrated human society and and derailed scientific progress. Only the individual human mind remains immune to the sophons. This is the motivation for the Wallfacer Project, a last-ditch defence that grants four individuals almost absolute power to design secret strategies, hidden through deceit and misdirection from Earth and Trisolaris alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead.

If The X-Files taught me one thing, it was to be afraid—to be very afraid—of escalators. I learned early to take the stairs, or else be consumed by Eugene Tooms. But the recently revived TV series taught me at least two things, in truth: that, and the fact that thinking of Earth as the cradle of all creation in the unimaginable vastness of the galaxy is an act of absolute arrogance.

I want to believe, in other words. Absent any evidence, however, belief is a difficult state to sustain. It necessitates a leap of faith I've never been able to take—though that's no longer a problem for the characters at the heart of the startling second volume of Cixin Liu's translated trilogy, as they, and humanity as a whole, have had that proof.

In The Three-Body Problem, our wildest dreams were realised in the same second as our worst fears: they are out there, and now that they know we're here, they're coming... coming to wipe out every last trace of humanity from the galaxy.

The thing is, they're going to take four hundred years to get here.

But when they do? We're toast, folks.

The assembly fell into a prolonged silence. Ahead of them stretched the leaden road of time, terminating somewhere in the mists of the future, where all they could see were flickering flames and the lustre of blood. The brevity of a human lifespan tormented them as never before, and their hearts soared above the vault of time to join with their descendants and plunge into blood and fire in the icy cold of space, the eventual meeting place for the souls of all soldiers. (p.43)

In this way, a great wave of defeatism sweeps the people, not least because they know that nothing they do now will have the slightest impact on the Trisolarans. The present-day generation's only potential legacy is laying out the groundwork for humanity to develop in centuries ahead. Today, the knowledge base just isn't there, nor indeed will it ever equal the quantum technology bolstering the Trisolarans' far superior force. That's because of the sophons: a mass of microscopic particles which interfere in certain experiments, establishing an energy-based barrier beyond which scientists simply cannot cross. We haven't hit it yet, but we will, one day. And then? Well, it'll be The End, my friends.
