Children of Ruin is ... okay. Children of Memory is not a good book, IMO. Both of these suffer from the same mysticism-used-to-spin-up-a-red-reset-button plot device plague that fundamentally guts Xenocide. Nowhere as bad as that, of course, but the unpleasant echoes are there.
As it happens I'm in the middle of the Architects series and while it has its distant whiff of Stainless Steel Rat[ß], on the whole the series and its universe have so far remained consistent.
ß: Stainless Steel Rat was notorious for repeatedly putting the protagonist into impossible situations and then whipping up near-magical pieces of technomancy that just happened to solve the problem of the moment.
I agree that Children of Memory is not very good, mostly because it repeats itself so much. That could've been handled differently while still advancing the plot. I LOVE the overall concept, and the author's skills describing Gothi and Gethli's unique kind of intelligence was great, so I was okay with it overall... but too much of it was just a slog. First book is by far the best in my opinion as well.
I read this as Stainless Steel Rat[ss], and was befuddled until I read the end of your comment.
The Tchaikovsky novella I really like is Elder Race. Technology-as-magic is done in so many places (Ventus is another favourite), and I usually enjoy it, but I felt that in Elder Race it was pulled off in an unusually elegant way.
Apart from "Solaris", which many probably know because there's been a reasonably well-known movie, I recommend "Fiasco" by the same author, Good science fiction where the aliens are very alien are hard to come by Stanisław Lem. Spoiler: It does not end well. The aliens are too alien, and the humans do what humans often do.
I feel this is one of the reasons I liked Fire upon the Deep with the group mind based Tines
Another sci-fi classic sorta made into a movie (Stalker).
uh uh, uh
But the concepts and writing are excellent... really engaging stuff. And by the end of the book I'd learned so much about spiders that I honestly felt less scared of them! Definitely not cured by any means, but a year on and I still fear them less than I used to.
I find his writing style really enjoyable, to the point that I really need to dive into his entire repertoire now.
And I agree, everything hes written has been worth reading.
Didn't really do much for all the other species though!
My first Tchaikovsky was children of time and TBH none of the sequels nor his other space operas were as captivating as that one for me.
Yet, I will read this one too. I believe that his ideas and stories are great in books and would never be able to make them into movies. So unique.
I can take SciFi that's at least either good story or good science. To this day I don't know why people recommend this author so much, even more than Watt's Rifters trilogy or Firefall. He is a "legal executive" who dropped out of zoology/biology. Explanations are just "nanovirus!" or "bioengineering!" and left at that.
Spoiler: the spiders make a space elevator and an asteroid catcher out of spiderweb; really. Stuff like this doesn't pass the suspension of disbelief for me. Reading it was quite annoying.
Feel free to downvote me, but if you do, I ask you the minor kindness to refute my points.
Edit: also "nanovirus!", what? All viruses are nano. And this virus being so complex it can't be too short, either.
