Match made in heaven or maid of dishonor? Tight-laced Rose Hensel arrives in Scotland for her best friend's wedding with a plan—to be the greatest maid of honor ever, let loose for the first time in years, and find out what Scottish guys really wear under their kilts. After meeting the best man, she thinks she found the man who checks all the boxes for a no-strings-attached romp among the heather. Lachlan Calder-Mackinnon knows how to show a girl a good time. Gourmet dinners in castle ruins, picnics among rolling hills, and a seaside escape create some unforgettable dates. But as the fling begins to morph into something more, an unexpected wedding guest threatens to ruin Rose and Lachlan's new romance. With a plane ticket in one hand and her broken heart in the other, Rose prepares to head home to reality. However, she's about to learn that what happens in the Highlands doesn't always stay there.
