I've been on a Larry Niven kick again and just finished Lucifer's Hammer. I last read it back in high school, so like 20+ years ago. Definitely hit differently than back then. Before that I had wrapped up Adrian Tchaikovsky's "Children" series. Most of those were pretty great. None come close to the first one though. I'm about halfway through Project Hail Mary with my daughter, so that's been fun. And I'm almost to the end of "Mort" by Terry Pratchett.
