"Latter-Day Sweethearts" by Mrs. Burton Harrison is a novel written in the early 20th century. The story revolves around Helen Carstairs, a young woman departing for a year-long trip to Europe, attempting to extricate herself from the discomforts of home life that include her father's recent marriage to a woman she despises. As she boards the ship "Baltic," Helen grapples with feelings of isolation and a secret past love for John Glynn, who now seems to be moving on with another young woman. The opening of the novel introduces us to Helen as she prepares for her journey, feeling the weight of solitude amidst the bustling crowd. As she contemplates her past, we learn of her discontent with her father's new wife and her failed romance with Glynn. Helen's thoughts are interrupted by the lively presence of another woman, who calls out to John Glynn as he makes his way through the crowd, igniting feelings of jealousy and lingering affection in Helen. Along with her companion, Miss Bleecker, Helen embarks on a voyage that promises to intertwine her fate with new characters, including the charismatic and engaging Miss Posey Winstanley, who represents a stark contrast to her own restrained demeanor, setting the stage for a story of love, identity, and social dynamics aboard the ocean liner.
