Genetically pure. Natalie Wright has never heard those words before. Neither has she heard of Dauntless, Abnegation, Erudite, Candor, or Amity. The Bureau of Genetic Welfare has asked Natalie to enter their Chicago experiment as a fifteen year old Dauntless member. They claim that she can be the turning point in the experiment, the one to set things right. So what will happen if she rebels? Prequel to all books including Four. All character and plot rights go to Veronica Roth.
