Summer. A flat, sleepy town. A main street, a river, and a riverside beach that soothe more than just the heat of a 1970s summer. Lalo and Bruno are teenagers—two adolescents doing nothing in the middle of nowhere. One humid afternoon, unannounced, Lisa arrives, shattering the town’s monotony. Until that moment, neither Lalo nor Bruno had ever seen anything like her. Thirty years later, far from the deceptive innocence of adolescence, Lisa reenters their adult lives with the same force she had at fourteen, stirring a new, uncontrollable fear—tempered, however, by the marks that time leaves on every living being.
