A Marriage of Convenience. A Betrayal That Cuts Deep. A Love Forged in Fire.

Clara McDougal has always been a free spirit, fiercely independent and defiant of the expectations placed upon her. So when she’s betrothed to Hamish McTavish—a man she hasn’t seen since he teased her mercilessly as a child—she vows never to give him her heart. The fiery beauty has no intention of being tamed, even if her marriage is meant to bring peace to two feuding clans.

Hamish McTavish, the brooding and handsome laird of Clan McTavish, isn’t thrilled about the match either. With his father ill and tensions brewing in the Highlands, his focus lies on protecting his people, not managing a willful bride. But when Clara arrives at his castle, dazzling and defiant, she stirs something in him he can’t ignore.

Before their wedding vows can even be spoken, tragedy strikes—the old laird is poisoned, and suspicion falls within the castle walls. Forced to put aside their clashing wills, Clara and Hamish must work together to uncover the traitor among them. As the shadowy mercenaries of the Black Veil close in and secrets are unmasked, their partnership deepens into something neither of them expected.

In a race against time, Clara and Hamish must not only protect their clan but also confront the undeniable passion that burns between them. Can they overcome betrayal and find love amid the chaos, or will their bond shatter under the weight of their enemies?

Passion, danger, and intrigue collide in The Highlander’s Oath, a sweeping tale of love and loyalty in the heart of the Scottish Highlands.
