The Sea Witch — Ruth Langan

The Sirens of the Sea:
Three proper English sisters who, upon the death of their father and brother in a shipwreck, take over the family business -- as privateers in the employ of Charles of England.

THE HANDSOME CAPTAIN WAS DUTY BOUND...

At the dying man's request, Riordan Spencer had pledged to watch over John Lambert's beautiful daughters. But when he arrived in Land's End, he never expected that Ambrosia Lambert would ignite a passion in him unlike any he'd ever known!

Though irresistibly drawn to the mysterious Captain Spencer, Ambrosia would not be swayed from her mission to carry on her father's legacy. Yet how could she convince her handsome protector that her need to remain a privateer to the king would not stand in the way of the powerful love that surged between them?
