Rinnaul's review about it, check it out!

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

Takes place after Rainbow Rocks, but was written before Friendship Games and does not take it into account.

It's morning in the human world, and Sunset wants to show Twilight something before the sun comes up.

After putting on the Element of Magic, Sunset Shimmer was shown just how much of a monster she really is. But that wasn't all the Elements did to her.

Sunset has now been forced to serve penance by answering any question truthfully and by doing anything asked of her, whether she wants to or not.

And she really doesn't want to.

Until all of the hatred in her heart is gone, Sunset is at the whim of her peers, unbeknownst to them of course. Can her new "friends" help her down the road to redemption?

If not, there's always that other Twilight Sparkle she keeps running into.
