Border Moonlight by Amanda Scott

Lady Sibylla Cavers is ripe for marriage, yet she’s rejected the first three suitors her father brought. When one of these suitors, the dashing Lord Simon Murray, rescues both Lady Sibylla and the small child she was trying to pull from the churning River Tweed, Sibylla begins to see Lord Simon in a new light. As he cares for her and the child until both are recovered from their near-deaths, she finds admirable – even lovable – qualities in Lord Simon. But political intrigue surrounding the powerful governor of Scotland will throw obstacles in the path if Simon’s and Sibylla’s budding love. Simon will fight for his inherited estate, while Sibylla will use all of her wits to protect their future together.
