The Dark Forest

I read the predecessor to the Dark Forest a few years ago (The Three-Body Problem by Cixin Liu), when it first came out.

I learned recently it was the first book in a trilogy, and all three books had now been translated (Cixin writes in his native Chinese).

The use of hibernation to enable plot timeline expansion was pretty neat ('main character goes into cryogenic hibernation for 300 years, accelerate all tech by that much time, wake up main character').  It definitely enabled a more interesting end to the story, with the appearance of the droplet and the Earth space fleet.

The novel provides a pretty interesting alternative solution to the Fermi Paradox.

The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high a priori likelihood of its existence, and by extension of obtaining such evidence

I'm kind of surprised that the characters in the book never mentioned it by name - maybe Fermi Paradox isn't known in Chinese (or there is a Chinese version of the same)?

I'm not sure if future books will explain it, but the droplet was a bit of a deus ex machina - everything else in the series so far appeared to obey (at least notionally) physics, or had a direct explanation as to what had changed or been discovered.  Giving the droplet an advanced material construction, to prevent it from being destructible, for example, is a great sci-fi deal.  Letting it not have intertia and move in any direction like the Yondu's Yaka Arrow in Guardians of the Galaxy seemed to begger believe and kill the story a bit.  Hopefully it's explained later.

The immediate drop into hard space facism by the crews of the surviving vessels was also ...interesting.  I know that's not necessarily unrealistic (old sea stories, pirates, mutinies, etc.), but is society really that fragile?
