Passion of a Highlander by Katy Baker

Thrown into the untamed wilderness of fifteenth century Scotland, Caitlin must navigate a treacherous path if she is to find her way home—all while guarding her wounded heart from the enigmatic and captivating Kai Stewart.
Caitlin Summers, haunted by a devastating trauma, seeks solace in the untouched landscapes of the Scottish Highlands. In her desperate attempt to escape the painful memories that torment her, she steps through an archway – and right into the path of Kai Stewart, the charismatic leader of a band of warriors. With a magnetic presence that both entices and unsettles her, he becomes an irresistible force she can’t ignore—even as her instincts warn her to be wary.
For Kai Stewart, the last thing he needs is a distraction, especially one as beguiling as Caitlin. With his band of brothers, he is on the brink of fulfilling a delicate mission, and the stakes have never been higher. But behind his stoic facade and playboy demeanor, Kai guards his own heart, shielding it from the vulnerabilities that love brings—especially when it comes to this intriguing lass from the future. Amidst the urgency of their mission and the dangers that surround them, Kai is uncertain if he can afford to let Caitlin breach the walls around his heart.
