After a daring escape from Cartagena, nine-year-old James can't wait to return to the familiar shores of Tortuga. Unfortunately, the Joneses and the pirateers didn't expect Dani to bring the admiral general's only son with them—whether he likes it or not. With the Spanish Navy on their heels, the pirateers can't stay on Tortuga, but getting off the island becomes much riskier when the privies attempt to kidnap their hostage.

And it isn't only the Spanish Navy pursuing the Joneses and the pirateers across the Caribbean. As they look for a place to hide, the pirateers find themselves trapped on the Isla de la Muerte—the Island of Death. With no way off the island, the crew quickly becomes lost . . . and James can't keep track of the number of ways they nearly visit Davy Jones's Locker while on the run.

Nothing goes as planned—because there is no plan this time. The Joneses, the pirateers, and their new friends battle through wild jungles, face a cursed volcano, and evade some very angry locals, all while undertaking the most dangerous rescue mission ever attempted on the one night of the year when the pirateers could possibly discover the third clue to the fabled Lost Treasure of Santa Maria. In this third epic novel, the Joneses and the pirateers' adventures just became a lot more nay on impossible. . . .
