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! My sister, Thea, had come up with a new way to torment me. She'd combined my two least favourite - travel and ghosts! Thea had heard rumours of a haunted pirate treasure buried on a desert island. And before I could say "Avast, ye scurvy rats", she'd dragged me into her treasure hunt!
