When Hazel Blum’s father gets a tenured job at a prestigious college, she and her family relocate from the hustle and bustle of Brooklyn to a middle-of-nowhere college town in Maine. With her mother, Claire, a clothing designer, and her father, Gus, an American Studies professor, Hazel and her 11-year-old brother, Wolf, spend the summer at the town pool, where they acclimate to their new lives and connect with the town’s sprawling community. That is, until a dramatic fallout on the very first day of her senior year tips the fickle balance of idyllic Riverburg and impacts everyone in her family.
