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!

It all started when my sister, Thea, discovered an old, mysterious map.
It showed a secret treasure hidden on a faraway island. In no time at
all, my sister dragged me and my cousin Trap into her treasure hunt. It
was an adventure I’d never forget…
