Among non-fiction what stood out to me was David Bentley Hart's
All Things are Full of Gods, great book also very fun to read written as a Platonic dialogue. To me one of the most compelling theologians today.
Bruno Maçães, World Builders. Good book on the impact of technology in geopolitics has been consistently interesting.
Among fiction re-read a lot of Lovecraft, noticed that I like the Dream Quest stories more than the horror these days which surprised me. But they're more compelling to me now because of how much you can see Lovecraft as a person in them.
The last three Dune books. Liked the last two about the Bene Gesserit a lot, was surprised how much I disliked God Emperor given the praise it gets, but it honestly reads like Frank Herbert posting twitter hot takes as a worm with no story
Mark Twain, The Mysterious Stranger. Among the best novellas I've ever read, very different in tone from most of his books.
Shūsaku Endō, Silence. Book about a Jesuit mission in early Edo Japan. My favorite Japanese book in a long time.
Among technical books, re-read The Mythical Man Month, probably more relevant than it ever was in an age of artifical man-hours added to projects. Robert Seacord Effective C, after not having written C in a long time. Really good intermediate level book for modern C. Also making my way through The Little Schemer as a replacement for advent of code in the second half of the month this year.
