The Captain’s Revenge by Nadine Millard

Lucas Townsend learned long ago not to entrust a woman with his heart; a lesson taught by the beautiful and aloof Anna Spencer. Having had his heart broken by Anna for being nothing more than a merchant’s son, Lucas dedicates his life to becoming someone she couldn’t look down on. Now, years later, he’s the toast of the ton and finally in a position to give Anna a taste of her own, bitter medicine…
Anna Grant has never stopped loving Lucas Townsend, contrary to what he believes about her. Having lived her life mourning the loss of love and envying other people’s adventures, the opportunity arises for Anna to have an adventure on her own.
Does she have the courage to seize the day, and will back the heart of the brooding Captain she used to know? Can the sins of the past be forgiven, and can love find a way to conquer all?
