For fiction I read a lot of Brandon Sanderson: the second Mistborn series, plus a few of the Secret Projects. I quite liked Tress of the Emerald Sea. Also currently reading R. F. Kuang's Katabasis which I'm really enjoying so far.

For nonfiction, I found Amanda Ripley's High Conflict to be excellent and insightful. I also finally got around to reading The Selfish Gene by Richard Dawkins; I expected it to be fine, but it far exceeded my expectations! On top of that, the edition I read also had "end notes" interspersed throughout the book with retrospectives from decades later, which only added to the book's richness.

Sanderson really writes incredible stuff. I read the entire cosmere last year and got a tattoo =)
