PIRATE MARAUDERS ALTERNATE UNIVERSE The seas know two things for certain: fear the storms, and fear the Blacks. For centuries, whispers have lingered in every pirate port from Tortuga to the Isles of Mist—a tale of a hidden cavern carved into the bones of the cliffs, where the infamous Black Family hid an artifact so powerful that kingdoms drowned trying to claim it. Captain James Potter has spent years chasing that legend.Alongside his first mate, Remus Lupin, and a crew of thieves, smugglers, and cutthroats, he has crossed treacherous waters, raided merchant fleets, and followed fragments of forgotten maps in pursuit of the lost Black treasure. At last, every clue points to a single destination: a cave untouched by mortal hands, hidden beyond jagged reefs and cursed waters. What James and Remus do not know is that the treasure has never been abandoned.It has been guarded.Deep within the cavern dwell two sirens—the last heirs of House Black. Ancient, beautiful, and far more dangerous than any sailor’s tale could describe. Sirius and Regulus Black have spent their lives protecting their family’s secrets, luring treasure hunters onto the rocks and feeding the sea with the remains.The arrival of the Marauders should be no different. But Regulus wants James Potter to himself, and Sirius wants Remus Lupin to himself.Until soul-bound bargains are struck, siren seduction takes over, ancient magic awakens, and the artifact at the heart of the cave begins calling to them all. After all, gold is easy to steal.A soul is much harder to get back.
