(started writing again, slow updates.)
After initiation, Tris is once agin attacked by Peter, who is hoping to get a better position than being a guard at the fence. When she goes to the Infirmary, she learns how much damage was really done. Tris, being the Dauntless she is, doesn't want to stay in the Infirmary for as long as she is required to. All Four wants is for her to get better.
But, when the unthinkable happens, Tris must bend the rules to save the ones she loves. The story is much better than the description, trust me :D (takes place directly after the initiation results are shown on the board for Dauntless. Attack on abnegation never happened. Mostly in Tris' POV) Disclaimer: I don't own Divergent or the characters, Veronica Roth does.
