As Cat's memory returns, he realizes that he has lived two very different lives: One as the son of the ruthless Bartholomew Thorne; the other as the recipient of friendship and kindness from Declan Ross and the crew of the Robert Bruce. Now Cat must choose whether to return to the ways of his notorious father and join the evil Merchant, or defy the Merchant and risk his life to save his friends. The best-selling Isle of Swords adventure continues in Isle of Fire as ancient mariners rise from legend and cut an all-too-real swath of destruction across the Atlantic. The newly formed Wolf Fleet scours the Caribbean, hunting the pirates they once called comrades. And in the pitiless winds of a monstrous hurricane, whole fleets will be blasted apart and devoured.
