Pirate Queen ANNE BONNY has a secret—a baby daughter named KATE! Anne, afraid that motherhood will undermine her fearsome reputation as the scarlet-haired scourge of the 18th century Caribbean, is having the baby raised by friends in the Spanish colony of Cuba, unknown to the crew of the Tigress—and that Kate's father, CAPTAIN CALICO JACK RACKAM. But when Anne wants to go to her daughter's first birthday—now behind enemy lines in the middle of Great Britain's latest war with Spain—she turns for help to the only person she can trust: fellow female freebooter MARY READ.

Together, the pirate queens will defy storms sharks, slave-catchers, a shipwreck, and the Spanish Inquisition...to fulfill a promise.

And, along the way, they might just plunder Spain's world-famed "treasure fleet."
