Besides J.K. Rowling, Andy Weir is one of my favourite authors. He is most known for The Martian (which was adapted into a film with Matt Damon), but he also published two more books: Artemis and Project Hail Mary.
I didn't go crazy for Artemis, but Project Hail Mary may be my favourite book in the last years. I recommend it to everyone, even if you are not into sci-fi, and I also suggest them to read it without knowing what it is about. Go totally blind, you'll love it.
