Enchanted by the Highlander by Lecia Cornwall is Book Four in the "A Highland Fairy Tale" Series. This is the story of Gillian MacLeod and John Erly. I have read the other books in this series (and loved them) but feel this can be a standalone book.
Donal MacLeod has loved all his wives and all his daughters but they do try to out smart him sometimes. Gillian is the shyest and quietest one of the family. Gillian seems to prefer to listing along with watching others. Gillian family has taken it among themselves to talk, think and answer for her leaving Gillian without a voice really. But Gillian does dream of having the relationship her sister's have with their husbands. Gillian is warned away from John who is an outsider to Scotland and only been there a few years. Everyone goes to John when they need something and counts on him but he is still thought of as an outsider. John was the son of a Noble Englishman but was disowned by his father and started a new life in Scotland. One night Gillian and John steal a kiss at a masquerade ball where they both are strongly affected by the kiss. But John didn't know who Gillian was and wasn't able to find her and almost a year passed since that kiss. But when John is asked to escort Gillian to a man that is to be her husband he starts to learn that it was Gillian who gave him that kissed. But along they way to their destination they run into danger and that makes for them to have more time together.
Really enjoyed their story!
