Is there any book you can read over and over again without ever getting sick of it? Do you discover something new every time you read it?
There are quite a few books I can read over and over. The Chronicles of Narnia are included in that, as are the Artemis Fowl books, the Harry Potter books, The Thief Lord, Things Not Seen, Paper Towns, and there are probably so many more that I'm not even thinking of right now. And, yeah, sometimes I'll notice things in a later reading that I missed in a prior readthrough. But that's all the fun of rereading a book! ^-^
