A few days after the event, Siena and I sat down to read Counting on Katherine for the first time together. Toward the beginning of the book, Siena turned to me and said, "That’s impossible. No one can know that much math. It’s a book." She flipped back to the two pages shown below.Surprised I replied, "Yes. It is a book. But she's a real person. It's a true story about her life." The look of surprise and wonder on Siena's face was magical.
