I'm 1 hour in, I think. Its pretty awesome :D

I finished it the other day and it only gets better.

A couple of friends were disappointed in the book itself, but the audiobook was much more enjoyable, I think. Zach Quinto is a lot of fun to listen to and I only noticed one word mispronounced the whole time! I don't know if it's just me, but visualizing seems much more active while listening than while reading. I should go back and listen to it again - especially for those extras not in the movie.
