My Champion by Glynnis Campbell
Sir Duncan de Ware is a sworn champion of the common man and a master of disguise. So when he finds plucky maiden-in-distress Linet de Montfort facing off against a notorious pirate, noble Duncan goes undercover to come to her rescue, despite her insistence that she can take care of herself. When the pirate abducts her, Duncan and Linet are caught up in a breathless adventure of danger and romance on the high seas. And soon Linet realizes her only hope is to trust her mysterious hero—with her life and her heart.
