Books for a lover of Andy Weir’s works?

I've been getting into reading more lately (finished college a year ago and have found it a lot more enjoyable since then,) and I picked up Project Hail Mary around a month ago upon recommendation from a friend. I COULD NOT put it down. I read it in two days — that just doesn't happen to me! I started reading The Martian since then and I'm loving it, too — does anyone have any recommendations for this style of writing? Not necessarily sci-fi, just anything that captured your imagination the way Weir has captured mine and tugged at your heart strings. I'm also a sucker for first person writing. I know this is a little vague, so feel free to suggest just about anything!
