Shrunk! - Ghosts On Board

More about the book

Victor, the ghost, is desperate to get off dreary Black Hall Island, so he steals a ride on an unsuspecting tourist boat back to Bywater-by-Sea. Two other ghosts--the terribly vain Flora Rose and the lonely but friendly Billy--know he is up to no good, so they follow him. Victor soon realizes that the town is not what it seems, and his new ordinary friends, Tom, Jacob, and Eric, have some very unusual powers. While Tom is distracted, trying to stop a corporation from building a theme park over his Field Craft hut, Victor sees his opportunity to take over the world.
