Suggest me another solid sci-fi book

Last night I finished reading Project Hail Mary by Andy Weir. Initially I was hesitant to read this book because I’ve never read any true sci-fi or fantasy books. I’ve always had a hard time enjoying books and movies that do not seem realistic to me and historically have read a lot of biographies, educational books and fictional thrillers. All this to say, I absolutely loved PHM and thought it wasn’t too overwhelming with crazy stuff going on and also was not overly technical. Overall was easy for me to enjoy. That being said, based on this information, does anyone have any recommendations on where I should go next in the world of sci-fi literature? I’m open to all thoughts, ideas and suggestions:)
