The Mortal Instruments: City of Bones

Judith Rumelt aka Cassandra Clare is best known for The Mortal Instruments Series of books that has been apparently very well received out west over the past 5-7 years.  But what does Cassandra Clare go through when the book goes onto the silver screen and the movie makers come to her with a dime a dozen changes.  I guess that’s a problem that most authors come up with and hence the term “True to the book”.
