Red Pizzas for a Blue Count (Geronimo Stilton #7)

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 troublemaker cousin was trapped in Transratania! And before I could
even squeak, my sister Thea dragged me along on her rescue mission.
Little did we know that Transratania is the land of vampire bats! Holey
cheese, bats give me mouse bumps! Why? Well, there's nothing a bat likes
more than sinking its teeth into a nice, juicy mouse...
