Jack Carlisle is a disillusioned 13-year-old boy. His mother is always away at work since his father left. He decides to run away, as he feels his mom won't miss him. As he is ready to leave, his nanny convinces him to read a 'magic book' that belongs to her. The book is about a pirate adventure on Magic Island. As Jack reads the book, he is sucked into the world and goes on numerous adventures with Prince Morgan, while fleeing the evil Blackbeard the Pirate. He is even saved by Lily, a beautiful mermaid, whom he falls in love with. Lily is given the power to turn into a human and accompanies Jack on his adventure. Along the way, Jack encounters sand sharks, a tree that grows the favorite food of the person who climbs it, and a cursed temple full of treasure. Jack also uses items he brought along with him in his "magic" bag to stop the pirates. Blackbeard was transformed into a gold statue by a guardian wizard. Eventually, Jack had to say goodbye to Lily, letting Morgan keep a rug embroidered with god & jewelry, and Jack is able to return home. He wakes up to his loving mother, and finds that his jeans are still torn and frayed and the flag on Prince Morgan's ship has transformed into his bag—signs that his adventure may have actually happened.
