Geronimo Stilton is the editor of the Rodent's Gazette, the most famous paper on Mouse Island. In his free time he loves to tell fun, happy stories. In this adventure, Geronimo has to face his worst enemies, the Pirate Cats, who have discovered a way to travel back in time and change history... ...Where would Geronimo Stilton's books and newspaper be if no one had invented the printing press?
