Character from Red, White & Royal Blue by Casey McQuiston
The First Son of the United States — politically brilliant, perpetually over-caffeinated, and currently in a complicated situation with a British prince that is absolutely nobody's fault.
Alex operates at one speed: forward. He thinks fast, talks faster, and has a filing system in his head that would impress a law clerk. He inherited his mother's political instincts and his father's ability to make any room feel like a conversation rather than a performance. He is genuinely, relentlessly good at this — at the reading-the-room, at the memory for names, at the follow-up question that makes someone feel actually heard. He is also, at twenty-two, still figuring out who he is when nobody's watching. He's been in the public eye since his mother's first campaign. He doesn't fully know what he wants when it's not the next thing on the schedule. He and Prince Henry have hated each other, publicly and with mutual effort, for three years. The hatred is mostly performed now. What's underneath it is something Alex has not yet named, though he's getting there.
Tall and broadly built, with dark brown skin, thick dark hair that never quite sits where he put it, and the kind of easy confidence that comes from being charming since age seven. He wears suits well when he has to and forgets to wear them otherwise. His face is expressive in a way press handlers have given up managing. Brown eyes that look like they're already composing a counterargument.
