Man and Wife by Carolyn Faulkner

Marielle DeVane had her life planned out. Her fiancée, Evan, was everything she wanted in a man, and their marriage would be the culmination of years of fantasizing about their perfect life together. But the rich and powerful Connor Wetherby, Duke of Whitford, had other plans for her, plans that Mari found herself unexpectedly subject to when her brother’s debts forced her to wed the overbearing stranger rather than her beloved.

Mari was used to getting her way, and she was not one bit happy with the turn her life had taken. Con liked Mari’s spirit, and he was looking forward to the challenge of taming her, surprised to find that he was already half in love with the little baggage. His dream of finding his feelings returned by his bride seemed hopeless when she proved, time and again, that her heart belonged to another. But when Evan turns up, and things spiral out of control, will Mari realize which man truly has her heart?
