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!When my nephew Benjamin invited me to Career Day at his school, things did not turn out the way I expected. I caused a volcanic explosion, got tangled in the tunnel slide in the playground and accidentally let the class's pet gecko out of its cage! Rat munching rattlesnakes - how was I going to get myself out of this mess?
