I have literally just started this book (on Scalzi‘s recommedation) and, so far, its a fascinating techno thriller, centered around a 15 year-old girl who has never been able to see.  The acknowledgments show that the author spent a lot of time trying to get it right – working with physicians, scinetists, blind people, to be able to tell much of the story through this character.  There is so much about how she hears the world, and it really resonates with me.  So far, and it’s very early in the story, there is really no music to speak of.
