"The Robots of Dawn" by Isaac Asimov
It is remarkable how relevant Asimov's books remain in 2026, the era of AI. In the third of the four books, we follow the detective again, now going to Aurora. Overall, a solid sci-fi novel, and mostly the only notable things I remember are that Daneel is the robot from the end of Foundation and that Solaria is now explained (although that was mentioned in the previous book).
Excited to see what's next in the fourth book!
