Mr. Stilton is a self-described "fraidy-mouse" who prefers a calm, quiet, comfortable life to one filled with adventure. He hates to travel, as he gets airsick, carsick, and seasick.
And yet, he is constantly finding himself in the midst of one heart-pounding adventure after another, along with his sister Thea Stilton (an adventure-loving photographer), his annoying jokester cousin Trapp Stilton (owner of the marketplace Cheap Junk for Less), and his favorite nephew Benjamin Stilton (a nine year old mouse hoping to work with his favorite Uncle Stilton someday). He chronicles these adventures in the popular Geronimo Stilton chapter book series.
According to the bio page included in each book in the series, Geronimo Stilton was born in New Mouse City, on Mouse Island, and lives there still. He is Rattus Emeritus of Mousomorphic Literature and of Neo-Ratonic Comparative Philosophy. He has run The Rodent's Gazette - New Mouse City's most widely read daily - for the past 20 years. In his spare time, Mr. Stilton collects antique cheese rinds, plays golf, and tells stories to his favorite nephew Benjamin.
