The Karate Mouse

Who is Geronimo Stilton?
That's me! I run a newspaper, but my true passion is writing adventure stories. Here in New Mouse City, the capital of Mouse Island, my books are all bestsellers! My stories are funny, fa-mouse-ly funny. They are whisker-licking-good tales, and that's a promise!

Moldy mozzarella! When my friend Bruce Hyena and his super-sporty cousin, Shorty Tao, entered me in the Karate World Championship, I couldn't believe it. I wasn't in shape, and I didn't know a single karate move. Plus, I only had one week to train! How on earth was I going to become a champion karate mouse in just seven days?
