Dressed in her wedding finery, and about to set out for the church, our heroine is nabbed by thugs, and is given the choice of being pressed once more into service by the Royal Navy Intelligence in order to pay off her debt to the crown for absconding with a naval vessel during her brief career as a pirate, or facing hanging. When put to her that way, Jacky opts for an extension of her brief life.
Her assignment: Disguised as a scientific exploration with naturalist on board, she is to sail her vessel, the Nancy B., to the waters off of Cuba, searching the area for interesting biological and botanical specimens, while in fact testing out a new diving bell which should enable her to reach depths deep enough to recover the treasure of a wrecked Spanish galleon.
The advantages: She will be captain of her own ship, she will be in a position to pay off her debt to the King, and best of all her fiancé Jaimy will be aboard the British vessel that will be accompanying the expedition.
The troubles: Crossing the bad side of a Spanish Lieutenant, running into some pirate friends who catch on the treasure seeking and want a cut, the kidnapping of one of her crew, and a couple of sea battles.
The temptations: Can Jacky’s better nature keep her on the straight and narrow when it comes to retrieving treasure from the bottom of the sea? And can she and Jaimy keep the vow of celibacy demanded by the Navy.
In conclusion: Another rip-roaring adventure filled with cock-fights, gambling, pirates good and bad, man- or girl-eating crocodiles, sexual temptation, and yes, treasure.
