Amelia Peabody lives in a small town where nothing changes. And that's just fine by her. After losing her big sister, Clara, a few years ago, Amelia can't handle any more change. But when she starts eighth grade, she accidentally receives a letter that Clara had written to herself. In it, there's a list of things she'd wanted to do before the end of middle school and never finished, like get on the softball team and throw an awesome birthday party on the lake. Amelia wonders if it's a sign from Clara. Maybe if she completed the list, her heart would stop hurting so much, and she could go back to being her old self. But as she makes her way through, Amelia finds that there's no going back, only forward. And she realizes she'll have to put her own spin on Clara's list to grow and change in the ways she needs to.
