Parents Need to Know

Parents need to know that there is a bit of cartoonish violence: characters getting bopped on the head with things like umbrellas, a mouse's tie gets stuck inside a conveyor belt, and a mouse is accidentally locked in a cold factory.

What's the story?

Geronimo Stilton, protagonist, mouse, and author, happens to be named after the very type of cheese that's mysteriously disappearing. With the help of his nephew, sister, and cousin he tries to get to the bottom of it. Will the makers of Stilton -- who think that Geronimo stole their name -- be satisfied once he solves the case?

Is it any good?


This series will get young and reluctant readers engaged with full-color illustrations and a large, appealing typeset sprinkled generously with "big" or "fun" words drawn in special ways. (The word, "embarrassing," for example, is written in huge red letters each time it's used.) Readers who are looking to expand their vocabulary will benefit from seeing the same words written out in the same way -- not that the book is too repetitive.

Other unique aspects of THE MYSTERIOUS CHEESE THIEF include highly detailed illustrations of Geronimo's workplace, The Rodent's Gazette, and a map of New Mouse City and Mouse Island itself, reminding the reader of similar detailed worlds captured in the Where's Waldo books and those by Richard Scarry.

Families can talk about...

  • Families can talk about reading big words. How did this book help? Was it the large print, the drawings, or both? The book also contains two recipes featuring cheese that might be fun for a family to cook together.

Good or Bad Book? (First Review)

It is a good children's book. It's exciting just like all Geronimo Stilton books. The only problem is that it's a bit violent. But it's supposed to be a fun, action-packed adventure book so it's not that bad. For me it's alright because it's not like he really got seriously injured or even worse died. So it's okay. Also, it can't be much of an adventure if there's not a FEW injuries. If the characters are just having good luck and nothing happens to them it's going to be pretty boring. There should be some excitement and mystery.

Too much violence

I have not read this book yet but I love the others! my favorite one so far is probably "cat and mouse in a haunted house" it was a little creepy but I like kinda creepy things. the scariest one so far was probably "the mummy with no name" my least favorite so far was probably "a cheese colored camper" but it was still awesome. my friend introduced me to the series. these books inspired me to write my own series! i haven't published any yet but the series is called "Hamilton Hamy" he's a talking hamster my first book will be "An Easter Adventure for Hamilton" if you like "Geronimo Stilton" you'll love my series. I'm 9 and I love Geronimo Stilton!
