Geronimo Stilton
series
Geronimo Stilton is a best-selling children's book series
written by Geronimo Stilton. In the series, the title character is a
talking mouse who lives in New Mouse City on Mouse Island. A
best-selling author, he works as a journalist for the fictional
newspaper The Rodent's Gazette. He has a younger sister named Thea Stilton, a cousin named Trap Stilton, and a favorite nephew, nine-year-old Benjamin Stilton.
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. The books are
written as though they are autobiographical adventure stories. The
original publisher is Edizioni Piemme in Milan, Italy. Scholastic, Inc. publishes the English language version.
The series originated in Italy and has become the most popular children's book series in that country. The books have been translated into 35 languages. Source: Wikipedia
