MC can make protection shield around himself and extend it out to protect others.
At a big do, dinner/charity auction, Princess Caroline of Monaco and her children are attacked in their hotel suite, I think in New York. MC saves them from harm.
I believe MC is a teen and quite rich/rich family himself.
I think this is a small scene in the middle of the story.
Not sure how MC gets his mind power for the shield or what else he does in the story, but not magic (I don't think).
