I read Three Body Problem four years ago, then bought the sequel, then … forgot about it.
I picked it up again this year, and realized that I had stopped at a certain “lull point”, and once I moved beyond it, things became far more exciting.
I just finished it today, and now I have to read the third one, because … I have to.
This is grand Sci Fi that took me two decades back, to when I first discovered Arthur C Clarke and Asimov. There is the same sweep of “big ideas” that are otherwise so hard to come by.
Liu Cixin is a master of this form, and one of those authors I know I’ll eventually read everything he’s written.
