Lots, but the big one right now is Artificial Intelligence: A Modern Approach by Russell & Norvig. I've had an ambition to read this cover-to-cover for a while, so I started it this year, with a goal of finishing by the end of the year.
Blood of the Old Kings, by Sung-Il Kim (translated by Anton Hur). Absolutely fabulous fantasy novel -- it's an about folks in an empire literally powered by the dead, and the folks fighting against its worst excesses. Very strange, mythological magic and excellent ethical through-line. This is a reread for me before I dive into the sequel.
