The One With the Wayward Duke by Eliana Piers

She’s the runaway bride. He’s a jilted groom. Neither knows the other, but they’re on the run together.

Lady Freya is about to marry the wrong man. So like any level headed bride would do, she runs. But she didn’t count on being rescued by the only man in the world with the one secret that would make her regret all of her running.
Burned by love, Tobias, the Duke of Vagenale, is weary of women. They’re manipulative, deceiving, and they don’t know what they want. So as he stands outside of the first wedding he’s attended since being jilted at the altar, he doesn’t expect to have to rescue such a woman bolting out of the church.

Fleeing the wedding includes an outlandish number of rescues, enduring a steamy, dreamy carriage ride, and sharing one bed. Will Freya find love on the run or will her hightailing ways spurn Tobias’s desire?
