This book is 100% created by the author. No AI was used. Laird Robin Mackay has been pushed for some time by the Clan Council to choose a wife from one of the clans with daughters and widowed sisters. He doesn't feel ready, but when Helena Ross arrives from the Sutherland clan to help her sister, Jena who is about to give birth to her first bairn, she catches Robin's attention. Then he is injured in battle and Helena must spend hours with him, helping him heal. He must marry for coin and alliances; she must return to Dornoch to take her aunt's place as the clan healer so the woman who raised her can ease back from her duties. With those responsibilities, there can be nothing between them. But the attraction is so strong, can they deny their duties to have each other?
