This is my first time reading Andy Weir and I enjoyed it! In the beginning, the fact that Grace doesn’t curse kind of took me out of it. Like this is a grown man, he can say fuck! But ig I understand since he’s a teacher. I liked his and Rocky’s relationship and the way they communicated. The science aspects of the book were easy to understand and follow along with. A great sci-fi book for someone just getting into the genre!
