Change of Heart — Margaret Eastvale

Anne had thought him lost to her forever

But now, after six long years, the news arrived that Lord Ashorne was alive-not killed while fighting in Spain as she had believed.

An irrational thrill surged through her... but the next moment Anne admonished herself for her foolish excitement. She knew that Lord Ashorne had never had eyes for anyone but her older sister. Knew, too, that he would never return her own childhood passion for him. His reappearance could make no difference to her.

But still her heart throbbed wildly in her breast....

Mills and Boon UK Edition:-

Mistakenly reported killed by the French in the Peninsular Wars, Edmund, Lord Ashorne, returns home to find that his beautiful fiancee Julia has married his rakish cousin Thomas, heir to the title. Thomas has himself died in Edmund's absence and Julia's younger and quieter sister Anne is now living with her. Anne has always idolised Edmund. To her his return from the dead is nothing short of a miracle. The spoilt Julia, determined to retain her title and wealth, decides that the simplest course is to marry her ex-fiance. Must Anne watch them falling in love all over again? Or can she trust her instincts, which tell her that Edmund has undergone a change of heart?
