Someone to remember / Mary Balogh.

"Matilda Westcott has spent her life tending to the needs of her mother, the Dowager Countess of Riverdale, never questioning the life of solitude she has spun for herself. To Matilda, who considers herself the aging spinster daughter, marriage is laughable--love is a game for the young, after all. But her modest, quiet life of order unravels when a dashing gentleman from her past reappears, threatening to charm his way into her heart yet again. Charles Sawyer, Viscount Dirkson, does not expect to see Matilda Westcott thirty-six years after their failed romance. Moreover, he does not expect decades-old feelings to emerge at the very sight of her. When encountering Matilda at a dinner hosted by the Earl of Riverdale, he finds himself as fascinated by her as he was the first day they met, and wonders if, after all these years, they have a chance at happiness together. Charles is determined to crack the hard exterior Matilda has built for over three decades or risk losing her once again.."--
