Alternative text for cover: Cover of The Legend of Chocolate HillsGeronimo Stilton is a mild-mannered, cheese-loving mouse who runs New Mouse City's biggest newspaper and would very much like a quiet life of editing and eating cheddar -- but between his adventure-seeking sister Thea, his hyperactive nephew Benjamin, and his loudly overconfident cousin Trap, Geronimo keeps getting dragged into globe-trotting (and occasionally time- or dimension-hopping) escapades against his will. Each book sends him somewhere new -- lost pyramids, pirate islands, outer space, prehistoric jungles -- where his reluctant courage and knack for stumbling into solutions save the day, cheese puns intact.
Created by Elisabetta Dami, the books are instantly recognizable for their playful, maximalist typography: key words burst into colored fonts, bold type, and illustrations mid-sentence, turning every page into something closer to a graphic experience than plain prose. That format, combined with short chapters and a friendly, breezy voice, has made the series one of the most effective bridges between picture books and longer independent reading for years.
With well over 100 titles published internationally (translated from the original Italian) and spin-off lines following Geronimo's sister Thea and other family members, Geronimo Stilton is a genuine global phenomenon -- reassuring in its warmth, low on real peril, and endlessly inventive in where it sends its reluctant hero next.
The main English-language series runs to 85 books as of The Legend of Chocolate Hills (2026), with book 86, The Hunt for the Secret Papyrus, expected in 2027. The wider franchise, including spin-offs, is far larger.
The books are almost entirely standalone, so you can start anywhere, though book 1, Lost Treasure of the Emerald Eye, is the traditional starting point.
No, it's ongoing, with new titles still being translated and published each year.
Thea is Geronimo's adventurous sister; she stars in her own separate spin-off series aimed at a similar age group, best read after the main series.
Roughly ages 7-10; the illustrated, color-typography format makes it a popular bridge from picture books to chapter books.
