He’s interested in aviation and is just getting into MSFS.
Like most of us at some point, we’ve had to learn, literally, how to fly in sims. Often we look back after many years of reading websites or books that have some breakthrough perspective or piece of advice and say,

I think he’d benefit from a good flying book, not needlessly technical, but with a good explanation of how and why things work in an airplane.
The FAA stuff is excellent in terms of technical content and diagrams. The writing is ■■■■. I am convinced they were written by AI. Stick and Rudder is a great classic. Maybe so old that it could be a turnoff depending on your friend’s tastes. Pilots are such left-brain people that they seem unable to write technically while maintaining the supreme beauty that is the greatest gift of flight. It’s a concoction of physics and magic. The subject needs the treatment of a true writer like @BeachAV8R or @Troll. I know of nothing modern in English that I could recommend.
I bought this for my son a fair few years ago. It was really appreciated as it kept his monitor at the right height while he played Left 4 Dead.

They are all available to read on the website.
Some are great, others are less useful and several have a narrow scope or software title they cover. Still worth browsing for someone new:
