IF MAE LOSES THE INN, SHE'LL LOSE EVERYTHING. Mae Benson was born to run the Sweet Island Inn. She cooks, she cleans, she laughs, she makes a mean pot of coffee and she always knows which beach to recommend to her guests. But suddenly, that way of life looks very much in danger. On what was supposed to be a happy day--the day her boyfriend Dominic gets down on one knee and asks her to marry him--Mae discovers that a collective of out-of-towners with bad intentions intends to usurp her business by building a competing hotel right down the street. And she's not the only one floundering. Other mysterious out-of-towners are bringing troubles of their own for the Benson clan--including an anonymous offer to buyout Sara's ownership of Little Bull restaurant (with some very strange strings attached). Holly's childhood friends arrive back on Nantucket for a tumultuous high school reunion with plenty of baggage in tow. And Eliza, meanwhile, is doing her best to keep her head above water--even as the anxieties she thought she left behind threaten to drag her beneath the stormy waves.
