The Lord Trap by Judith Lynne

He can afford to indulge Lady Viola in a bit of kidnapping.

Not forever, of course; after all Mr. Waite lost fighting the wars, he doesn’t believe in forever.
That’s fine with Viola; neither does she.
Lady Viola doesn’t make mistakes. So her yearning for the lord of her dreams can’t be wrong. Everyone in the ducal palace is about to discover that secretly, she’s ruthless… because she’ll do anything to have him. Even marry someone else.
Bradley Waite found solace drifting with England’s winds. He’s not prepared to be kidnapped by his best friend’s delicate, determined sister. He may despise the rules of polite society, but he knows better than anyone Lady Viola’s brother is a crack shot.

If the lady must be married to have the man of her dreams, so be it. But Waite must escape her lord trap before she learns what kind of man she’s captured.
