Could a person memorize a whole book?

Specificaly, just for fun and because it is my favorite Narnia book, I have memorized the first page of The Voyage of the Dawn Treader by C.S. Lewis. I was thinking that I probably could memorize more if I worked at it. Do you think I could possibly memorize the whole book, or at the very least, the first chapter to where I could recite it? Call me a freak if you want to, but I think it would be awsome to try!
