Miss Lydia Montague's life takes an unexpected turn when she learns of an inheritance that could grant her the independence she's always craved. But there's a catch: to claim it, she must travel with the brooding Maximilian Ashcombe, Duke of Hasting, to his remote estate. Neither is thrilled by the arrangement—Maximilian sees it as an inconvenience, and Lydia is determined to prove she doesn't need his help.

As the journey unfolds, danger shadows their every step. Bandits, sabotage, and unforeseen mishaps force them into close quarters, and the tension between them ignites into something neither can deny. Lydia's fiery spirit and Maximilian's unyielding nature clash and complement, creating a bond that grows stronger with every mile.

But when a shocking secret about the inheritance comes to light, their fragile trust is tested. With rivals plotting against them and their hearts on the line, Lydia and Maximilian must decide if their journey will end in separation—or if love will prove the ultimate destination.

One Duke of a Time is a thrilling Regency road trip romance filled with passion, peril, and the undeniable pull of two hearts destined to find their way.
