Query: Great Book

Bought this book brand new in a bookstore when I was 15. Wore it out. Found another copy in a used bookstore when I was 30. Lent it to a friend and didn't get it back. Bought another copy on Amazon when I was 45. I'm getting older, but this book isn't. Timeless story and a great read. If you buy it, you will finish it in one sitting and then start it again. I imagine I'll be buying another copy at 60!
