The Gilded Age glamour of Harper St. George's The Heiress Gets a Duke would definitely turn into a gorgeous, resplendent movie. August, the heiress to an American iron working fortune, wants to take over the company, not be married off to a man who can advance her family's standing. When her younger sister is pressured to marry an impoverished duke, August won't hear of it — but her outspokenness lands her in the duke's eyes instead, leading to a clash between two strong-willed, practical people who will deny they're falling in love even as it's happening.
