Pursued across the Eternal Sea by the Ghoul King, an ancient and very magical ship arrives in the town graveyard. And then things really start to get weird.

Jenny's first year of high school becomes way more problematic than it already was when an ancient and mighty ship that sails the Eternal Sea (and looks suspiciously like an old beat-up bottle you could fit in your backpack) just shows up in her room, sitting on her dresser. This bottle... or ship... believes that Jenny is its long-lost "Captain." Even though she isn't. Or at least she doesn't think she is.

Whether Jenny is really the Captain or not, she'll need to figure out how to be a hero really fast. Because the Ghoul King has followed this magic bottle across the Eternal Sea and now he is here, hiding in the town graveyard. If he gets his hands on the ancient and mighty ship, many worlds will fall. Now it's up to Jenny, along with her little brother, Jed, his dumb dog, and Jenny's best friend Ethan (who for some tragic reason is now Isabel Warner's boyfriend). Very sorry about what might be about to happen to your world, but just so you know, none of this is Jenny's fault. Because honestly, if you ever wondered about your sweet old grandmother's mysterious past, your first guess probably wouldn't be "maybe she was sailing a magic ship through countless adventures on the Eternal Sea, then moved to the assisted living center across town, where she was supposed to teach me the truth about the universe, the nature of reality, and how to control that magic ship if it ever just showed up some day… but she just forgot." Pretty unlikely, right? Unfortunately, that's exactly what was happening to Jenny.
