A Totally Not Divergent Divergent story

So what if Tris was involved in the Erudite Faction, and Caleb became faction-less because he didn't pass dauntless training? What if Four came from the Erudite faction, but transferred to dauntless at the choosing ceremony? What if Tris was the Erudite leader, but never actually got killed? What if Dauntless became all that Eric wanted it to be.. harsh, merciless, and mean?
This is my first fanfic, and I'm not good at summaries so please read.
It gets better as it goes on. 4Tris will be included somewhere closer to the middle/end, just not sure when.
There's a lot of scenarios that might make you want to pull your hair out-so brace yourself. I'm sorry in advance if the book seems to move too fast, again this is my first fanfic and I'm in need of an editor.
I hope you like it, Happy Reading!!
