Caitlin sounds like she looks exactly like Allie's little sister (who arrives at the beginning of Book 3.) Or Cousin Esme, whom you will also meet in the new book.

She sounds like a great kid. And that's a toss-up for temptation--we need great minds in research, but also in the classroom. Of course they discourage kids with too high a grade point average from teaching HS or grade school. Or did when I went through.
