Geronimo and his friends travel to his cousin Stevie Stingsnout's wedding far away on Cheap Change Hill and run into trouble.

I was just minding my business at home when I got a telephone call. It was my uncle Samuel S. Stingysnout, inviting the whole Stilton family to creepy, faraway Penny Pincher Castle for a big surprise. Moldy mozzarella -- I'm not much of a traveling mouse, and I hate surprises. But Thea, Trap, and Benjamin were going, so I couldn't say no. I could tell this was going to be one super-spooky trip! -- from Amaozn.

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 race to be the first to find the legendary gem. The jewel was protected by thousands of ancient booby-traps -- a 'fraidy mouse's worst nightmare? Would I make it through with my fur?

When Geronimo's sister, Thea, heard that there was a secret hidden in Mouse Island's most famous painting, the Mona Mousa, he knew he had to crack the code!

"The Thea Sisters are in Kenya on a photo safari! The mouselets love exploring the magnificent landscape and learning about the animals on the reserve they're visiting. A cub has just been born, but while they're there, he's kidnapped! It's up to the Thea sisters to rescue him in an adventure across the savanna."--P. [4] of cover.
