As I read I encounter parts of the book that are tweaked or portrayed differently in the movie. Of course there are going to be some, but there are vital actions and thoughts that characters have that help showcase who they are as well as develop the story and relationships between them which is lost in the movie The Bone Collector. For example, the way Amelia and Rhyme respond and interact with each other is much more personal in the book than in the movie.
Currently I have read 37% of The Bone Collector, about a third of the way into Chapter 13. I am enjoying every page.
