Chapter 15 consists of a text conversation between Grace and her grandpa. She tells him about Hank, the feud with Ellie, and her new interest in buttons, and he gives her updates on renovating the old mill. Lastly, she explains how buttons have become a fad at school, and he reminds her to take good notes on the phenomenon, telling her that he doesn’t know what will happen, but he believes that she will “be right in the middle of it” (96).

Grace’s mom drives her to school on Monday, and they talk about the rift between Grace and Ellie. Grace asks her mom if she still has any friends from sixth grade. Her mom doesn’t because she moved around so much and never tried to keep in touch with friends from different places. She supposes that she could find people now because social media makes it easier to do so, and Grace thinks that “easier is a very nice idea” (100). At school, Hank is standing out front, and seeing him makes Grace smile, because walking into the building will be easier at his side.
