The Princess Bride held the title of "my favorite book" for close to a decade. It was the first time that I really got the concept that life isn't fair -- I read this as a teenager. You can't imagine the pressure that was released with this statement, when you feel that the world is against you and ITS NOT FAIR. Well, duh, life is what you make of it, life owes you nothing.
It may have been the commentary more than the story that stole my heart. Don't get me wrong, I loved Wesley and Buttercup - I still haven't given up hope for Buttercup's Baby!! - I loved the humor of the story. But it was the advice. The voice of a father that I didn't have in my life, but so desperately needed, that sums up why this book was my favorite. When I became stronger and knew my own mind and didn't need the voice of a man in a book to build me into a person, this book slipped down my list.
