Lizzie is bright, cheerful and almost ethereal in her beauty, without having any knowledge of it herself. When she married Neil, a minister for the Church of Scotland, it was because of his looks, spirit and intent to do good. He wanted to take the most difficult job he could find. Setting out for St Kilda with a man she barely knew, pregnant with his child, she had no way of knowing if she was heading for adventure or disaster. For Neil, the move is about atoning for the sins of his past, testing and strengthening his own faith as he encourages others. His love and admiration for Lizzie are constantly challenging him - is he blessed with her love or is she a temptress taking his concentration from his faith?
