I don’t think I can contribute much to this thread, but I read a lot of science fiction books, and I track them on The Storygraph. If you’re curious about the titles, here they are:
Sometimes I chat about them with the people on the Discord server associated to the YouTube channel “Words in Time”:
This is a great contribution! Thanks for the hint! 
How do you like their recommendations?
One promise that had me join Goodreads quite a long time ago was that they’d supposedly find you new reading material based on what you read so far. They never made good on that promise, and with a large and varied enough library I don’t even know how that would ever work. Ideally, I’d want to find something that’s reminiscent of a specific author, or belongs to a certain sub-genre, etc.
I now switched to tracking my books in an app called Bookshelf, and while it seems to offer some social features, it’s more geared towards cataloging your collection and remembering where you put or whom you lent something.
Initially, I was dissatisfied with their default recommendation algorithm.
I was only interested in “serious” science fiction (novels in which the narrative flows through scientific themes) but the recommendations included a lot of irrelevant material. I even perceived some kind of systemic bias.
Later, I was able to get exactly what I wanted by spending a few minutes personalizing my preferences. There is an option to specify preferred themes, and once I filled out that field, I received excellent recommendations!
Did those suggestions help me discover interesting books to add to my to-be-read list? Some, but not many. My main recommendation apps are Meet New Books and, more recently, ChatGPT (which I have instructed to provide very specific science-fiction-related metrics).
What hint? 
Sorry, this was a bit misleading. I meant that your links and your list are useful.
Thanks, that one seems pretty good, though so far I wasn’t in the mood to give it more than a cursory spin. I guess my biggest fear is that it spits out books already out of print, and therefore hard to obtain.
I recently finished the Remembrance of Earth’s Past trilogy by Liu Cixin, and it may or may not fall into that category, depending on what you’re looking for specifically. Though perhaps it’s leaning more towards philospophy than science. At any rate, it left me pretty impressed. Each volume has a bit of a different topic and tone to it, and different characters too, but it’s more or less the complete history of human civilization from 1967 until the heat death of the universe. Quite imaginative, and while the 2nd and 3rd book do not quite reach the level of suspense found in the first, they are still expertly told and full of surprises.
Obviously, the timeline is rather condensed and restricted to the view point of not too many different characters, but that makes it also more relatable and tangible than an account in the abstract could ever by. Fully recommended.
Thanks for the recommendation! I haven’t read anything by Liu Cixin yet, but The Three-Body Problem has been on my TBR list for a few months. From the little information I’ve gathered, I expect to love the kind of stories he writes.
From the way you describe Remembrance of Earth’s Past, it has some Olaf Stapledon vibes. I discovered the author some time ago while researching for old, very inventive science fiction books that “predict” long-term human evolution and civilization.
It’s difficult to pinpoint exactly what I’m looking for in a science fiction novel, but generally, I look for a plot that advances by relying on scientific principles.
For example, I recently finished reading Asimov’s The Gods Themselves, and the underlying concept (an apparently free and inexhaustible source of energy) directly impacts how the plot evolves.
Another example of such a narrative is pretty much every novel by Greg Egan. I have read Diaspora and researched his other works, and he definitely focuses on that type of scientific curiosity that holds my attention.
A few days ago, I asked for recommendations on Reddit exactly about this type or works. Here is the post. As expected, Egan received many upvotes, but the thread contains many other interesting suggestions.
I read (or rather devoured) Tad Williams’ The Navigator´s Children, now that it is out in German. As far as classic fantasy goes these days, I haven’t seen anything better, but even Williams shows some influence from a Song of Ice and Fire, when it comes to political intrigue, violence, word count, and sex.
The first two thirds of the book conclude the main story, with excellent pacing, and plenty of twists and turns. The last third is what I’d call “The Scouring of the Shire”, and like the first 200 or so pages of the first book, it feels drawn out and excessive. Yeah, it’s nice to have all loose ends tied up, all remaining secrets spoiled, and the next “trilogy” set up too, just in case, but it lacked the excitement and high stakes of what came before.
All things considered, I still like Shadowmarch better than Osten Ard, perhaps with the exception of Brothers of the Wind. With a bit tighter writing, and one or two subplots focusing on court politics instead of adventure cut, The Last King of Osten Ard would have been fantastic. As it is, it’s merely great 
.
I am at page 530 out of 700 (not counting the appendix) of the English version of The Navigator’s Children because I don’t want the book(s) to be over. I welled up when a story arc initiated in Brothers of the Wind was tied up in this book. I can only fear what is to still come…
On the bright side, I still have a bunch of unread short stories and English editions of Otherland and Shadowmarch that are waiting to be (re)read. And then I might start all over again.
I’m also trying to start in Tolkien’s The Silmarillion after watching Rings of Power. In the appendix, I stumbled upon a queen nick-named “Kementari”, which sounded familiar. it is the name of the Sithi city on Warinsten
Oh, and I read a book about Monkey Island by Nicolas Deneschau, but no one here is interested in that, right?
But the braid pulling is the whole essence!
I’m currently reading De buitengewoon geslaagde opvoeding van Frida Wolf. It’s quite amusing. The protagonist (Frida)’s father is a prison director who’s some kind of kleptomaniac intellectual.
Also yesterday I read something called Vampi, from the current Vampirella Humble Bundle. A bit odd but kind of cool.
