The Valmiki Ramayana, translated by Bibek Debroy. I have only browsed this so far, but it is definitely worthy of mention.
Peter Guardino, Dead March: History of the Mexican-American War. The link brings you to my commentary.
Samanta Schweblin, Fever Dream: A Novel, [Distancia de Rescate].
Navid Kermani, Wonder Beyond Belief: On Christianity. My review is behind the link.
Claire Tomalin, A Life of My Own. Ditto, a real favorite.
Robin Hanson and Kevin Simler, The Elephant in the Brain: Hidden Motives in Everyday Life. At first this was slated for my 2018 list, but it turns out the Kindle edition is out now, so it gets to make both lists.
The New Testament, translated by David Bentley Hart.
Homer, The Odyssey, translated by Emily Wilson. I haven’t read this yet, but it is getting consistently rave reviews.
Karl Sigmund, Exact Thinking in Demented Times. Again, a review is behind the link.
