Geronimo Stilton meets The Flintstones in this NEW, prehistoric spin-off series!

Welcome to the world of Cavemice! Geronimo Stiltonoot, Geronimo Stilton's ancient ancestor, lives in the village of Old Mouse City, where he is the editor of The Stone Gazette. Every day, he carves the news into slabs of stone, because the printing press hasn't been invented yet! Life in the Stone Age is full of adventure, whether he's dodging meteorites or trying to avoid a sabertoothed tiger or ferocious T-Rex. He's chiseled all of his outrageously funny tales into stone so everyone will know what it was like to live in the Stone Age!

In this adventure, Old Mouse City is in an uproar. The most precious artifact in the Old Mouse City Mouseum - the Stone of Fire - has been stolen! Geronimo Stiltonoot and his cavemouse friend Hercule Poirat are on the case. It's up to them to retrieve the stone from the ferocious Tiger Khan and his band of fearsome felines!
