Tish - Certain books on Amazon are part of the Kindle Lending Library. You can "borrow" a book and read it then you "return" it and then you can borrow another one. You are only allowed one borrow a month, of course, you can keep the book longer than a month if you need to. Once the book is returned you can borrow another. The Gone Girl is not one of those books right now. Do you think it is worth $12.99 for the Kindle or maybe I should check out my public library?
