Highlander’s Forbidden Desire by Kenna Kendrick

It was so wrong to feel in such a way for his father’s bride.
Elaine McRob knows her destiny; wed the man her father chose for her. As an obedient daughter, she has no other choice.
Her betrothed is a kind man and a powerful Laird, but two big problems arise. First, he is just as old as her sire. Second, his son is someone she met once before. And this Highlander makes her heart race.
Finlay MacCallum cherishes family and honor above all else. So, when his widowed father decides to marry again, Finlay couldn’t be happier for him.

But when he sees his future stepmother, he is stunned. The lass is no stranger to him.
As flames of desire ignite and jealousy arises, Finlay is torn between giving in to Elaine’s temptation or staying true to his father. Unfortunately, their mutual longing won’t be a secret for long. With the wedding approaching, Finlay and Elaine must find a way to stay apart before father turns against son, and a forbidden affair plunges the clan into chaos.
Wanting her was forbidden, having her was his ruin…
