Being a duke has its challenges, but Duke Leontius "Leo" Arkwright of Seaforth never imagined this would be one of them. One ill-advised sip of a mysterious potion lands Leo in his wife Nerissa’s heavily pregnant body—and her in his. Suddenly, the stoic duke is navigating a swollen belly, enduring relentless cravings, and grappling with the indignities of social duties as the "duchess." Nerissa, meanwhile, is relishing the chance to experience life free from the aches and limitations of pregnancy, taking on Leo’s ducal responsibilities with unexpected ease. And she doesn’t miss the opportunity to remind Leo just how much she endured. “I’m a man, Nerissa. A duke. Do you have any idea how absurd that is?” Her eyes twinkled with mischief as she leaned forward. “Oh, I do. But you’re mistaken about one thing. You’re not a duke right now, Leo,” she said serenely. “You’re a duchess. The pregnant one, to be precise.” Leo had mocked Nerissa’s pregnancy cravings—lavender-honeyed ham and strawberries dipped in pickles—but now finds himself waking her up at midnight demanding something even more ridiculous: sugared onions and mustard toast. To Nerissa’s glee, his complaints about the “unbearable discomfort” of corsets, waddling, and emotional outbursts come full circle when he realizes her pregnancy was more challenging than he ever acknowledged. As the due date looms, the couple is forced to confront their new reality, discovering compassion and love in the most unexpected ways. Can Leo survive labor? Can Nerissa survive Leo’s theatrics? And will the strange old woman ever return to fix this mess before their child arrives? Filled with humor, heart, and utterly absurd situations, The Duke Who Became Her Grace is a rollicking Regency romantic comedy about love, understanding, and the hilarity of walking (or waddling) a mile in someone else’s shoes—or corsets.
