It's the last Fall Formal at Canterlot High before graduation, and the Rainbooms are looking to make it the best one ever. Sunset Shimmer is especially excited to enjoy a celebration with her friends... until she finds herself drawing the ire of the Rainbooms once again.
Someone with Sunset's face and name is lurking in the shadows, and they're out for revenge. With this dangerous new foe doing everything she can to frame Sunset and ruin her life, Sunset calls on Princess Twilight Sparkle to help her clear her name and stop the mysterious doppelganger. But as tensions rise, Sunset is faced with the grim possibility of never having the ones she called "friends" trust her again... and her double's plot may be more sinister than she realizes.
I originally published this story in 2018 to the MLP:FiM wiki in the style of a synopsis for a special. I finally decided to write the full version after several people asked where it was after reading the synopsis version. The original page can be found here (do not read if you don't want spoilers for this fic.)
WARNING: I wrote the original synopsis in my teen years, and it gets edgy. There's a lot of Sunset suffering and out-of-character Rainbooms. If you don't like Anon-a-Miss stories, you probably won't like this either.
