Lexine and Alex Addensworth find themselves orphaned after a fatal attack on the family ship. Pirates have destroyed everything their parents have worked for, and the wreck separated the pair, leaving them to survive on their own with a sea between them. They are both strewn into two very different worlds; Lexine is taken in by a rowdy pirate crew with an attractive yet mysterious captain who is hiding a dark secret, and Alex sets off for revenge through the kingdom's navy. Will the sister and brother pair find each other? Or will they both fall victim to the misadventures they find themselves in? Let alone, can they trust the new allies they make, or are they dangerous?
