This is the second book in The Timeline Series; an adventure series in which Francis, Will, and Jessica travel through time on a mission to alter their futures. While trying to return to their present, the trio find themselves face to face with cutthroat pirates. They befriend a boy who has become an orphan at the hands of the pirates and decide to help him rebuild his family business by going on a search for legendary treasure. The journey is as dangerous as the pirates that are also after the treasure, and Francis, Will, and Jessica must use all their tricks to survive so they can try once again to return to the future.
