The Black Morass (Pirates of the Coast #1)
Barbara Devlin

En route to Jamaica to join her father, after her guardian dies, Lady Madalene Davies departs Boston in anticipation of a new life in a foreign land. When her ship is attacked and set afire, she is left for dead, until an unlikely savior comes to her aid. Brash and bawdy, her flawed hero defies the conventional ideal, as he is no knight in shining armor and seems forever intent on shocking her, yet she cannot resist the lure he presents. What happens when danger lurks in unexpected places, faith is broken, and Madalene must rely on Jean Marc to stay alive?
