Run run run…That's what twelve-year-old Annie loves to do. When she's barefoot and running, she can hear her heart beating . . . thump-Thump, thump-Thump. It's a rhythm that makes sense in a year when everything's shifting: Her mother is pregnant, her grandfather is forgetful, and her best friend, Max, is always moody. Everything changes over time, just like the apple Annie's been assigned to draw. But as she watches and listens, Annie begins to understand the many rhythms of life, and how she fits within them.
