Tanzanite's Castle Full of Books

Born a despised gypsy and tricked into a life of brutal debauchery, Lola Blaise quickly learns the harsh ways of the world, and of the men who inhabit it. But in the New World waits a different sort of life, full of danger and passion, where one false move could mean death: a life of piracy.  On the island of Nassau, Lola earns her keep as a prostitute until she lands a place on the Revenge, a ship captained by the infamous Blackbeard, the greatest buccaneer who ever lived. To survive the lethal treachery of a pirate’s life Lola must use every hard-earned skill in her arsenal—and become the woman she was always meant to be.
