Geronimo Stilton is a best-selling children's book series published by Edizioni Piemme of Milan, Italy, since 2000. Scholastic Corporation has published the English version of the series since February 2004. Although the series credits its title character as the author, the idea was originally thought of by Elisabetta Dami. On older novels, the copyright is issued to a pseudonym "Geronimo Stilton"; this was changed on newer books. The books are intended for readers in the 6–12-year-old age range. In the series, the title character is a talking mouse who lives in New Mouse City on Mouse Island. A best-selling author, Geronimo Stilton[2] works as a journalist and editor for the fictional newspaper The Rodent's Gazette. He has a younger sister named Thea Stilton,[3] a cousin named Trap Stilton,[3] and a favorite little nephew, nine-year-old Benjamin Stilton.[3] Geronimo is a nervous, mild-mannered mouse who would like nothing better than to live a quiet life, but he keeps getting involved in far-away adventures with Thea, Trap, and Benjamin, and sometimes Aunt Sweetfur. The books are written as though they are autobiographical adventure stories. The work of an Italian author under a pseudonym, the series has become the most popular children's book series in Italy and the books have been translated into 35 languages.
