Geronimo Stilton is a bestselling series of children's books that features a talking mouse who lives in New Mouse City on Mouse Island. Geronimo is nervous and mild-mannered and would like nothing better than to live a quiet life, but he keeps getting involved in far-away adventures with his sister Thea, his cousin Trap, and his nephew Benjamin. The series originated in Italy, the dreamchild of author Elisabetta Dami, and has since been translated into 35 languages.
