In Dubuque, Iowa there is a very famous landmark called the Fourth Street Elevator. It is definitely a great tourist attraction and has been in operation since 1882. One summer day, Maggie took her grandsons, Jake and Max, for a ride up and down the elevator. They had so many questions about the history of the elevator, so they went on the internet to learn more about the history of it. After the first ride, every time the boys came to visit they had to take another ride up and down the elevator. About that same time, the first J.K. Rowling book, Harry Potter and the Sorcerer's Stone hit the bookstores. The boys loved it when Maggie read the book to them. They even wanted her to make the Harry Potter caps, which she did. That was the starting point. Maggie's mind starting spinning with all sorts of ideas about a book based on the Fourth Street Elevator and inspired by the over-all theme of Harry Potter and the Sorcerer's Stone. The book includes some historical background but very quickly turns into an imaginative and magical tale of two boys and a delightful white cat, Master Graves.
