Highlander's Captive (Called by a Highlander, #1)

She must return to her time. He keeps her heart captive.

While chaperoning a high school trip to the Scottish Highlands, Amy MacDougall descends into Inverlochy Castle dungeon. Deep in the crumbling ruins, she touches a magical rock and travels through time to 1307.

Infiltrating the castle, Highlander Craig Cambel imprisons Amy. A MacDougall, she’s his clan’s sworn enemy. But when he’s forced to marry the fierce beauty, he surrenders to desire. Amy needs to return to the twenty-first century, but her feelings for Craig are growing stronger every day. Will the pull of centuries divide them, or can destiny bind them across the ages?

It's the year 1307, and she's the enemy.
