From the backwaters of Georgia to the taverns of Philadelphia, Fin Button is the talk of the colonies. The British say she's a pirate. The Americans call her a mutineer. The crew of the Rattlesnake call her the most unlikely thing of all: captain. But with the Revolution on the verge of defeat, the Congress offers Fin a deal. If she can free a noblewoman held captive by pirates, the French may be persuaded to join the war. Fin's reward? A full pardon. Along with Jack, Topper, and the mysterious Armand Defain, Fin sails the Rattlesnake to the Mediterranean Sea, half a world away. Their destination is Tripoli--home of the savage corsairs and slavers of the Barbary Coast. To win the prize, Fin will need the help of an ancient seafaring order, the Knights of Malta and the resolve of one faithful knight could alter more than just the outcome of the Revolution. It could mend the heart of a lonely girl and give rise to an American legend.
