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!Finally, I was about to leave for a relaxing vacation all by myself. I was ready to kick back and connect with nature. But somehow, my peaceful trip turned into a crazy treasure hunt in the beautiful Black Hills of South Dakota with the entire Stilton clan in tow! Our journey even included a hot-air balloon ride to Mount Rushmore. Holey cheese! This was one adventure I'd truly remember.
