The book "Divergent", was written by Veronica Roth. It is the first in a trilogy of books.In Divergent, the choices you make define you more than anything else in life. Making decisions and choices is a major theme in Divergent. Examples of decisions and choices in the book include the adolescents having to choose a faction, the situation when Tris killed Will and when Tris' mother, Natalie, sacrificed her own life for Tris. At the Choosing Ceremony, Tris had two options; stay with her family in Abnegation or start a new life by transferring to a different faction. .
Tris' aptitude tests were inconclusive which meant she was a suitable match to Abnegation, Erudite or Dauntless. This made her decision to choose a faction even more complex. To decide whether to stay true to your heritage and live in the faction you grew up in or to abandon your family and start anew is quite possibly the biggest decision the young people in Divergent had to make. Tris accepted that she would never fit perfectly anywhere; she simply had to form her own path through her choices, one step at a time. I believe this was included because as adolescents we need to understand that we don't always fit in and that it's important to make decisions for ourselves. This type of message is inserted all through the book which is why the text is relevant to teenagers. A famous quote the characters are supposed to live by is 'Faction before blood.' Caleb believes in this quote and displays it just the night before the Choosing Ceremony, when he tells Tris something she thought she'd never hear her brother say. These words were "Beatrice, we should think of our family. But, we must also think of ourselves." Both Tris and Caleb stay true to this mantra and true to themselves by transferring faction, leaving their family behind. Tris chooses Dauntless because she feels it will allow her to discover her true self and Caleb chooses Erudite to stay true to his own identity.
