You can't undo the past, but you can learn from it. Two years after the Faction system is rebuilt in Chicago after the reign of Jeanine and then the factionless, Tobias Eaton is on his way to visit Evelyn, his mother, in the new Faction 6 (the old factionless) council building. However, he never makes it there, because on his way he finds an abnegation girl with a knife to her stomach, about to end her life. Seeing the need, he steps in to investigate the odd situation. He quickly finds that she has a past ironically similar to his. Will this girl change his now dull view of the world. [yeah, sorry, I'm terrible at descriptions]
