Goodreads: A woman inherits a beach house, along with a series of weekend guests, while butting heads with the irritable (and irritatingly handsome) man next door, in this sparkling new escape from Jane L. Rosen.
 
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.
 
Steadfast in her path since college, Addison is determined not to let this detour on Fire Island throw her off track. But soon, between the revolving door of weekend visitors and the up-and-down relationship with her neighbor (and his adorable dog), she finds herself in unfamiliar territory. Should she try to pick up where she left off—or embrace entirely new possibilities?
