When a Zoom disaster upends Addison Irwin’s decade-long career at a posh Manhattan advertising agency, things look bleak for the thirty-something mid-western transplant. But an unexpected inheritance from an aunt she barely remembers --- a property on Fire Island, complete with guest house and artist’s studio --- changes everything. While debating whether to stay or sell, Addison learns that she’s also inherited her aunt’s list of eclectic guests, tying her to the island for seven summer weekends. Eager to convince Addison to keep the house rather than let a new buyer build a monstrosity in its place, the neighbors welcome her to their laid-back community. Well, all except the moody guy next door, who seems intent on glowering his way through life. Addison is determined not to let this detour on Fire Island throw her off track.

So when the unthinkable happens to Julia, rather than following the light at the end of the proverbial tunnel, she chooses to spend one last summer near those she loves most. As she follows her adoring, novelist husband Ben to their --- unexpectedly full --- home on Fire Island, she discovers the ripple effect her life has had on the trajectory of so many.
