In the summer of 1978, eleven-year-old Caleb Walker spends his days along the bends of a slow Tennessee river with his dog, Blue, learning the quiet rhythms of the water and trying to stay gone until the porch lights come on.
At home, his father's drinking moves through the house like weather-sometimes distant, sometimes close enough to change the shape of an evening. Years earlier, Danny Walker lost his younger brother to the river, a grief he never learned how to carry and never truly escaped.
Over the course of one long Southern summer, Caleb begins to understand how grief can settle into a family quietly, shaping the way people love one another, the things they learn to hide, and the silences that follow children long after they've grown.
