Reminds me of SW... By the time I saw TESB I had already read the comic adaptation of the film. Then I ordered the ROTJ storybook ( like a kiddie novelization ) - which was due to arrive before the film came out - through my school, but the order got screwed up/delayed. A friend down the block had it and let me look at it, but the weird thing is he would only let me read the very beginning and the very end. I am significantly more spoiler-averse now. Also, I believe the novelization of ROTS was released before the film.
