Giving things the proper name is important, which is why Stephen thinks that it's time to update the definition of "pirate." They've got a bad rep, and maybe they deserve some of it, but Stephen still likes a few pirate traditions, like bandannas and eyepatches - he's just not that into stealing things from people. He has the perfect new word: piventurate. A sailor who passionately seeks adventure. When he gets suspended from school for doing proper piventurate-in-training things (using sticks to practice sword fighting), his mother doesn't let him sit around doing nothing, instead she takes him to a museum. At the museum everything changes. Stephen finds himself in a strange new place, face-to-face with a real pirate. A pirate ghost. Captain Sapperton needs Stephen's help to cross to the other side, and his former ghost crew are intent on making sure Stephen follows through, whatever it takes.
