Repairing A Broken Heart

Can you run away from love?
She thought Harry loved her and she was prepared to wait for him, but Lyla is devastated when he becomes engaged to someone else. He writes to explain his reasons and she wants to forgive him, but all she can think of is escape.
She persuades her father to send her to Ireland to help in purchasing horses for the family business. In spite of meeting the engaging Finn and all sorts of other new people, from camp followers to the Colonel's lady, Lyla still falls asleep with Harry's folded and re-folded letter against her breast.
Then her father calls her home. Will she be able to take up the threads of her old life? Or has Ireland has changed her for ever?
Is it possible to repair a broken heart?
