Highland Passage by J.L. Jarvis
What would you risk to find love?
Mackenzie Cooper has had it with romance. On her way home from another blind date arranged by her well-meaning sister, she is caught in a snowstorm. While maneuvering the twists and turns of the icy road, Mackenzie loses control of her car and crashes into the rocky hillside.
When a rugged Scotsman pulls her to safety, Mackenzie is sure she must be hallucinating. Through the storm's fury, he takes her to shelter in one of the mysterious stone chambers scattered throughout Putnam County, New York. Snowbound, Mackenzie must wait out the storm with this strange, kilted man who claims to be a Highlander from eighteenth-century Scotland. By morning, she not only believes Ciarán MacRae's story but has also lost her heart just in time for him to kiss her, promise his love--and then vanish.
Unable to forget him, Mackenzie returns again and again to the stone chamber, hoping to unlock the secret of Ciarán's disappearance. But if she does, she will have to decide whether her fierce feelings for Ciarán are worth abandoning all that she knows to travel through time to find her gallant Scotsman.
A Note on the Content: The Highland Passage romances fall on the sweet end of the romance spectrum. Although not explicit, they may contain sexual situations and mild profanity.
