A decade after her father's death brought her back to Amber Cay for what was supposed to be a week, Sloane is fully who she once swore she'd never become: a Calloway who stayed. The final season is framed around a single, symbolic summer — the marina's fiftieth anniversary — and the quiet question that's been building since season one: what happens to Calloway Marina, and to Amber Cay itself, in the next generation. Isla's teenage daughter shows early signs of wanting nothing to do with the family business, echoing Sloane's own younger self. Faye's investment expertise pulls her toward a life half in the city, half on the coast. And Sloane and Beckett, now raising a young daughter of their own, must decide whether they want her to inherit the marina's beauty or its weight. The season closes not on a crisis, but on a choice — the same dock, the same golden light, a different ending than the one Sloane wrote for herself at eighteen.
