"Geronimo Stilton : 48 The Mystery In Venice" Summary of the book:
In each Geronimo Stilton book, another funny, cheesy adventure is always right around the corner. Each book is fast-paced, with lively full-color art and a unique format kids 7-10 will love.

When my friend Petunia Pretty Paws gave me a crystal figurine of a boat as a gift, I had to accept it. After all, I have the biggest crush on Petunia! But oh, was that crystal boat ugly! So I wasn't too sad when my cousin Trap accidentally broke it, especially when I discovered a piece of paper inside with a mysterious message from someone in Venice, Italy, asking for help! A gentlemouse never ignores a request for assistance. So I, Geronimo Stilton, would do whatever it took to save the day! (goodreads.com)
