I'm a big fan of Joss Whedon's series Firefly, and the movie conclusion Serenity. It's so disappointing that the series was canceled, because I could quite happily watch it nightly. In any case, thirsting for more Firefly led me to look into what was available in written form. The novelization of Serenity by Keith R.A. DeCandido is one of the items I decided to check out.
So far it's good. It's not one of those novelizations that differs from the movie in fundamental ways, such as plotline. (As a kid, I was horribly disappointed when I read the book Honey, I Shrunk the Kids and discovered it diverged from the movie in several places.) Also, the narration fits the feel of the series and the character dialogue, too - although it's third person omniscient (meaning it's third person but follows many different character's thoughts and feelings), the tone of the narration suits whichever character's point of view is being used at the moment.
In other words, the narration "talks" like the character it's following would in the show, and I really like that. I can literally hear Mal's, or Jayne's, or River's voice in my head as I read. It's definitely not easy for a writer to assume so many drastically different voices at different intervals throughout the book, not to mention to decide which voice is the most appropriate for a particular scene, but DeCandido has done admirably.
This is quite possibly the best novelization of a movie that I've seen (the exception being, naturally, books that were written first), and a definite must-read for any Firefly fan.
