The Three-Body Problem by Cixin Liu
“The science is very convincing and up to date, but as a science fiction novel The Three-Body Problem feels like something written in the days of Asimov and Clarke. Devotees of hard science fiction will find a lot to like, since many modern science fiction novels don’t have even half the ideas on display in The Three-Body Problem, but the characterization is too contrived for the story to have the emotional impact it deserves.”
