Professor Arton Daghdev had always wanted to study alien life up close. Then his wishes become a reality in the worst way. His political activism sees him exiled from Earth to Kiln’s extrasolar labour camp. There, he’s condemned to work under an alien sky until he dies. Kiln boasts a ravenous, chaotic ecosystem like nothing seen on Earth. The monstrous alien life interacts in surprising, sometimes shocking wa

on “Ask HN: What did you read in 2025?” ↗While reading Pushing Ice a very common thought I had was "did Reynolds want to do a Rama sequels?" Shroud is great, easy recommendation. Another of Tchaikovsky, Alien Clay, also great, also very alien.
on “Rendezvous with Rama” ↗I don't think I've been disappointed by anything from Adrian Tchaikovsky, tbh. Alien Clay and Service Model are also great.
on “Newly discovered spider builds spring loaded snare to catch ants” ↗Adrian Tchaikovsky’s “Final Architecture” series is lots of fun. I also highly recommend the two “Bioforms” books. For standalone novels, I liked “Alien Clay” and “Doors of Eden” the most. For novellas, “Walking to Aldebaran” and “Elder Race”. Thank you for recommending “Implied Spaces” as well. Walter Jon Williams seems like a new author for me to follow.
on “Accelerando (2005)” ↗The Stars are Legion and Alien Clay are the two best sci-fi books I've read in the last year and I don't think they've shown up on any lists, although the latter is another first contact book by the author of Children of Time which has…

It follows a scientist sentenced to a prison camp on a planet teeming with bizarre lifeforms. So far, it hasn’t drawn me in the way Children of Time did, though I’m only about a…

The context was this was about his book about exobiology and authoritarian governments, Alien Clay.

James is about a man who escapes from slavery, fends for himself in the wilderness, violently avenges his wife and daughter, etc. Alien Clay is about a man who rebels against an evil government, is sent to a prison camp in space, bangs his boss (a woman), starts another rebellion, etc. I haven't read these books so maybe the descriptions are…

No idea where he could possibly go from there, but if he does, I'm going along for the journey. (Honorable mention: Alien Clay. Dishonorable mention: Service Model.) Eric Flint's "Fenrir" was a fun BDO near-future space adventure. (As was John Sanford's Saturn Run, but that wasn't a 2025 book I read.)
on “Ask HN: What did you read in 2025?” ↗I read Alien Clay and another book by him, which it turned out is basically the same book, which I found disappointing.
