My Lady Pirate — Elizabeth Doyle

SWEPT INTO HIS EMBRACE...
A shipboard raid is Isabella's first taste of adventure--and danger. Raised in a convent, she knows nothing of the world beyond its walls. Yet even in her innocence, she cannot believe the darkly handsome pirate captain is anything but a ruthless blackguard. Until he displays his honor in a stunning act of bravery--and Isabella decides that the man whose kisses have awakened her deepest desires is really a hero at heart.

...AND INTO PASSIONATE ADVENTURE
Marques has never encountered a woman like Isabella. The blonde beauty heats his blood, but her trusting spirit inspires a fierce protectiveness that takes him by surprise. He won't allow her romantic fantasies to be destroyed by the grim truth of life aboard his ship. But when he finds Isabella in the hands of a savage Mediterranean privateer, he vows to claim her as his own lady pirate...and as his one true love.
