It's after Tris' death but what if she didn't die and has been living in the real world for a year and a half. What happens when Tobias shows up and pulls her from a world she thinks she knows so she can return to help her old life in the city.

Happens after Allegiant. Tris died but did she really? FourTris love! Horrible summary please read! Also some facts might be off since I have yet to finish the book, but I had this idea and I knew how it ended so yeah.
