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! Rancid rat hairs! I'd been spending so much money lately, I had none left in the bank! Even worse, when my grandfather found out, he sent me off to Moldy Manor. There, miserly Uncle Stingysnout would give me a crash course in saving. Yikes! Could I learn to be less wasteful without turning totally stingy?
