Forever Her Scot by Scarlett Scott

A marriage of convenience between a Scottish duke and an American heiress turns sizzling in this final entry of USA Today bestselling author Scarlett Scott’s delightfully wicked Dukes Most Wanted series.

American heiress Madeline Chartrand has a problem. Her matchmaking mother is determined to secure an aristocratic husband for her, despite her wishes to the contrary. Lachlan Macfie, the newly minted Duke of Kenross, has an even bigger problem. He’s just inherited a moldering Scottish estate, crumbling castle and all, without the massive funds necessary to repair and run it.
Fortunately, Lachlan has the perfect solution—a marriage of convenience. It’s a simple enough arrangement. Madeline gets the duke her mother hopes for, and Lachlan can restore the estate with the help of her vast dowry. All he has to do is convince the stubborn and delectable Miss Chartrand that marriage is the answer to both their quandaries.
