Project Hail Mary by Andy Weir. Great stuff, a little surprisingly imperfect in some of the non-sci-fi (pure writing) aspects, but absolutely great as far as the hard sci-fi aspects and it's a more or less instantaneous read. I got it at the bookstore this weekend for myself while Christmas shopping, finished the whole thing by Christmas, and then gave it to someone who I'd forgotten to get a gift for.
Prequel by Rachel Maddow. Great stuff like always.
The System: Who Rigged It, How We Fix It by Robert Reich. I haven't started it but I love his stuff on Twitter and the person who gave it to me swears it's good.
