When Emily Clairmont's husband is tragically struck down by typhoid fever after only a few months of blissful domesticity, Emily finds herself heartbroken and completely alone in the world. Having lost her mother in childbirth and her father right before her marriage, she has no choice but to seek a position as a governess. She reaches out to her husband's family solicitor, Quinn Westbourne, hoping that he may be able to help her. Quinn takes one look at the young and beautiful Emily and decides that a job as a governess will not do. He writes instead to the father-in-law she's never met, and when Leopold Clairmont offers her a place in his home, Quinn agrees to escort Emily to his isolated refuge in St. Kilda. But he did not anticipate how challenging it would be to keep his distance from the grieving widow when all he wants to do is take her in his arms and console her. The two forge a friendship on their journey, and Emily begins to wonder if she could find solace and a live a comfortable life as a widow in her new home. The tiny island of Hirta in the remote cluster of islands known as St. Kilda off the Scottish coast is wild and beautiful, her father-in-law is warm and welcoming, and her sister-in-law offers her much-needed female companionship, but the island is also full of secrets. When Emily learns things about her husband that he never revealed, she wonders if she ever really knew him at all. Torn between her devotion to her departed husband and her growing feelings for Quinn, Emily must decide whether her heart belongs to the living or the dead and find the courage to act before it's too late.
