On an obscure island in the North Atlantic Ocean, a cheerful pixie named Pudding is about to make history by launching the world's first submarine. Unfortunately, the maiden voyage, which should be an easy cruise around the ocean for the young inventor and her three friends, quickly turns into an unexpected adventure. With events of mythological proportions happening all around her, Pudding soon realizes that her newest invention may land her in the history books for an entirely different reason.

Rescue has come at last for Pixiedom’s most infamous inventor, but it takes a form that she hardly expected. Rather than offering Pudding and her friends a sense of relief, their rescuers bring the dismal news that a pixie very dear to Pudding is being held captive by extremely dangerous forces in a far away city called Troy. Facing nearly impossible odds and a host of dangerous beings, Pudding embarks on an adventure where she discovers that the sinister events at Troy go deeper than a simple kidnapping. It will take all of her genius and inventing prowess if she hopes to save not only the unfortunate prisoner, but the world itself.

In the days following the events at Troy, Pudding and her friends are treated to the harsh reality that getting home isn't going to be as easy as they expected. With the magitorium on her trail and a dangerous enemy out for revenge, Pixiedom's most infamous inventor has to pull out all the stops to get everyone home in one piece, and hang on to the freedom she so desperately desires.
