Rescued by the Buccaneer. Pirates of the Jolie Rouge, #1

Kidnapped by a crew of ruthless pirates, Frederica's only hope is the French buccaneer who saves her life. All he asks in return is her submission... When Frederica Beauchamp boards a ship for the Americas in 1665, she dreams of a life filled with adventure, but she gets more than she bargained for when her passenger ship is attacked by pirates. The heartless men kidnap her and force her to serve their captain-a fate that might be worse than death.
After the pirates bring aboard an injured man found floating in the sea, Frederica tends to his wounds and learns that he is Gaston Galette, a survivor of a shipwrecked vessel. Gaston seeks her help to overthrow the vile captain, but when their plan goes awry he is forced to use all of his wiles to save them. As he watches the proud, willful Frederica bow to his authority, however, Gaston worries that her growing hold on his heart will be his downfall.
He knows he cannot take a woman with him when he returns to his ship and crew, but when Frederica offers herself to him, Gaston realizes that he may never be able to let her go.
