When Lily's blind dog, Lucky, slips his collar and runs away across the wide-open blueberry barrens of eastern Maine, it's Salma Santiago who manages to catch him. Salma, the daughter of migrant workers, is in the small town with her family for the blueberry-picking season. After their initial chance meeting, Salma and Lily bond over painting bee boxes for Lily's grandfather, and Salma's friendship transforms Lily's summer. But when Salma decides to run in the upcoming Blueberry Queen pageant, they'll have to face some tough truths about friendship and belonging. Should an outsider like Salma really participate in the pageant-and possibly win?
