Who is Geronimo Stilton?That’s me! I run a newspaper, but my true passion is writing tales of adventure. Here in New Mouse City, the capital of Mouse Island, my books are all bestsellers! My stories are full of fun – tastier than Swiss cheese and tangier than extra-sharp cheddar. They are whisker-licking-good stories and that’s a promise!One day, my friends and I, Geronimo Stilton, made an amazing discovery. We found a huge oyster with an enormouse pearl inside! I was so excited about this extremely rare, precious pearl that I wrote a special feature about it in The Rodent’s Gazette. That article attracted lots of attention – both good and bad! The enormouse pearl was in danger of being stolen. Would my friends and I be able to protect it?
