Rescuing the Irishman : Christmas Rescue Series Book 17
Angela Lain, V. McKevitt

This was the man whose rider-less horse led Dee Melrose to him, lying injured in the snow. Over the next days she tended him. He could remember nothing, but gradually it came back, and she learned who he was.
It took time for Finnbar Connelly to remember his own name, let alone what he had been doing when he fell. All he knew was that he’d been rescued by an angel. To stay with her was all he wanted in this life. Then he remembered his dirty little secret.
