Divergent: Switched

Tobias is about to chose. He has always been too selfish for abnegation. Tris transferred from abnegation two years ago, and she is no longer a scared little girl. She had found strength in her new faction. Dauntless the brave. When Tris meets Tobias, or Toby, as he goes by as soon as he gets in the Dauntless Compound, she realizes how much she has missed out on, playing the role of Six, the cruel instructor. Will she finally change, or will the years of being cold at heart and a secret keep her from warming up?
