This book is not an installment of the Divergent series, but it is a prequel from the perspective of the character Tobias.  This book is written by the New York Times bestselling author, Veronica Roth.  The setting of this story takes places in a dystopic society.  How this book relates to the theory is pulled from the main character Tobias.  He is a relatable character to young adults not only because of his age, but because he represents a sense of youtful independence.  This kind of independence is one that young adults see themselves as holding within them. From the age responses, none of the adults labeled young adults at "independent."  However, some of the young adult responses did.  In the story, Tobias is seen breaking away from his former life to create his own.  This type of action reflects independence.  He was beginning to live on his own and take care of himself.  Also, Tobias is depicted as a very strong character, and those young adults who can relate to him would feel empowered by the similarities they hold with him.  This case is especially true when Tobias is seen surviving and succeeding in the dystopic society.
