Enter the world of Geronimo Stilton, where another laugh is always right around the corner. Each book is a fast-paced adventure with lively illustrations and a unique format kids 7-10 will love. It was my most thrilling adventure yet! My old friend Professor von Volt had discovered the location of the famous Ruby of Fire. And before I could let out a squeak of protest, my sister Thea had dragged me into the race to be the first to find the legendaryem. The jewel was protected by thousands of ancient booby-traps - a fraidy mouse's worst nightmare! Would I make it through with all my whiskers?
