Their Summer Season follows Ember Hawthorne, a photographer who returns to her wealthy family’s Topsail Island estate after her parents’ deaths, intending to settle the estate quickly and leave for good. Instead, she learns she’s legally trapped on the island for months, forced to confront grief, unfinished family business, and a past she deliberately escaped. Complications multiply when her ex-fiancé plans a lavish wedding at the estate and the influential Prescott family—long entwined with her father’s dealings—moves even closer into her life. As Ember navigates legal pressure, small-town scrutiny, and the suffocating weight of expectations, she’s drawn into charged, very different connections with the Prescott brothers: familiar comfort, sharp conflict, and quiet, unsettling understanding. Over one pivotal summer, Ember must decide whether she’s merely surviving a season—or finally rewriting the story she’s been living by obligation rather than choice.
