When you're with Geronimo Stilton, it's always a fabumouse adventure!Holey cheese, what an adventure! I was off to Niagara Falls with my nephew Benjamin's class. It was a beautiful place -- truly one of the most amazing sights I'd ever seen. But unfortunately, I was surrounded by mischievous young mouselets who were determined to send me over the Falls in a barrel! Oh, would I ever make it back to Mouse Island alive?
