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.

Talk to your kids 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.
