Perfect science fiction. It's pretty tough in places but never at the expense of the story. The whole thing is surprisingly coherent, and I did find myself right at the edge of understanding it at times, but always managed to find my way back to a narrative that at least made sense to me.

If you have even a slight interest in civilisation, technology, space-faring sci-fi then I wouldn't hesitate to recommend this.

I am looking forward to some not-sci-fi though. I loved this but it's a lot and I can do without looking 18bn years into the future for a while.

Letting you know I exist, and letting you continue to exist, are both dangerous to me

What a wonderful sequel to The Three Body Problem. A coherent, plausible, and utterly desperate future imagined through the lens of totally assured destruction of our species.

Probably the best ending to a second-in-a-trilogy that I've ever read. The reader is Luo Ji's Wallbreaker and it's perfect (that's not a spoiler - if you're interested in sci-fi, this trilogy is essential, in my opinion).

Super intriguing story throughout, and I'll immediately move onto the next one.

The only criticism I have is that the prose feels very clinical and cold, and I can't tell if it's the translation, the author, or just how books are written in China.
