Pirate Queen Anne Bonny has a secret--a baby daughter named Kate! The baby's being raised by friends in Cuba, and Anne, worried that her reputation as the scarlet-haired scourge of the Caribbean would be undermined by motherhood, has been hiding the truth from the crew of the Tigress, and even from the girl's father, Calico Jack Rackam. But Kate's first birthday is coming up, and Anne wants to be there. The problem is, there's a war on, and Cuba's behind enemy lines. So Anne turns for help to the only person she can truly trust--fellow freebooter Mary Read.

Together, Anne and Mary will defy storms, sharks, shipwreck, and various murderous cutthroats to fulfill a promise. And along the way, they might just plunder Spain's fabled Silver Fleet...
