Book vs. TV Show

     So far in the series I have found two major differences.  In the book Sutton is dead and narrating from death and in the television show Sutton is alive and hiding.  This suprisingly does not make too much a difference to the story other than Sutton cannot help Emma understand more about her past life.  The second difference that I found was the main mystery.  The main idea of the book is to find Sutton's murderer while in the book Emma and Sutton have a major common goal of finding their birth mother.  One minor difference between the two are added and subtracted characters.  In the book the Twitter Twins are introduced but do not exist in the television series.
