The Wandering Earth, by Liu Cixin (author of the famous Three Body Problem trilogy), hard(-ish) sci-fi.
It's a collection of short stories named after the first story, Wandering Earth. I'm still only in the very beginning of the first story but it already introduces some really interesting ideas which is what I loved about the Three Body Problem. So I'm sure I'll like the rest. If you liked TBP, I'd definitely recommend.
On my phone:
Hyperion, by Dan Simmons, 1989, sci-fi/space opera(?)
Does it need introducing?
Anyway, since I don't read on my phone all that much and usually only in short bursts (meaning I usually read each page at least twice), for the past month, maybe even more, I've been slowly getting through the first chapter (The Priest's Tale) but once it got to the cruciform thing, I had to finish that chapter in one sitting. Now I started the second chapter, The Soldier's Tale, and can't wait for being mind blown again. Already got amused by this:
There were tales of cadets receiving fatal wounds in the OCS:HTN sims and being pulled dead from their immersion creches.
So... If you die in the Matrix, you die in real life too. Is that where they got that idea from? :) It's always fun reading through old sci-fi classics and finding likely inspiration for newer stuff or even inventing something that everyone else then uses later. Asimov's Foundation was all like this, so many things that eg. Star Wars straight up copied (eg. Trantor/Coruscant).
