This is a very good book because of the many adventures Leo and his uncle take, including their buggy ride to Leonardo's house and a meeting with a stone carver. I like how Leo completely changes his mindset in the story; he goes from annoyed at being there to excited at what is to come next. The plot's set up is amazing, the events flow right into each other. You never know what’s going to happen next or what trouble they are going to get into. Uncle Leonardo is a bit unpredictable at times and you never know what’s going to come out of his decisions. I would recommend this book to almost everyone.
