Project Hail Mary
I always like books by Andy Weir, especially how he can intertwine scientific facts with the plot. Very few authors I’ve read can do that well. Highly recommend for those who are interested in space travel, futuristic technology, and fate-of-the-world type situations.
Everything That Remains
I don't know what to put here yet. It's a good book, published at a small publisher (you won't find it at Chapters).
