"There are so many ways to be brave in this world. Sometimes bravery involves laying down your life for something bigger than yourself, or for someone else. Sometimes it involves giving up everything you have ever known or ever loved, for the sake of something greater. But sometimes it doesn't. Sometimes it is nothing more than gritting your teeth through pain, and the work of every day, the slow walk toward a better life. That is the sort of bravery I must have now."
~"Allegiant" By: Veronica Roth
In the series, tris is described as a sixteen year old girl with dirty blond hair and later, she gets three tattoos of birds representing her family members. (It does not say much about her appearance in the book)
