How the Scot Was Won - Desperately Seeking Duke, #2.5

To win a Scot's heart. Agnes St. James has no wealth, no status, and no suitors. Thankfully, she's happy with her family, her friends, and her beloved shop, the place to buy fine silks in Edinburgh. Felix Duncan has a thriving legal career, connections, and ambition. What he doesn't have, despite his father's prodding, is a wife. Fortunately, he's content with that. Until their paths cross, and suddenly both realize they want more.
Agnes is astonished-and thrilled-that such a charming, handsome fellow is flirting with her. Felix is astonished-and bowled over-that his friend's younger sister has grown into such a clever beauty. It looks like Fate-until a scandalous indiscretion and a shocking inheritance threaten to spoil any chance of happily-ever-after.
