Fifteen-year-old Mia Thompson is sent to her grandparents’ lake house in Saugatuck, Michigan, to escape the fallout of her parents’ divorce. Expecting boredom, she instead finds unexpected connection with her cousins Ben and Sophie, quirky family traditions, bonfires, canoe trips, and the healing rhythm of Lake Michigan’s waves. Amid storms, skipping stones, and late-night truths, Mia confronts her anger and uncertainty. What begins as a summer of escape becomes a season of rediscovery—learning that family isn’t perfect, change isn’t always loss, and sometimes the deepest healing comes from the simplest things: water, laughter, and choosing to stay connected.
