Sunset Shimmer's life has always been full of mistakes; But she rose to the occasion and kept fighting, willing to improve herself, every single time.

And now she is celebrating five years of being an Alicorn Princess-- Happily married to Twilight Sparkle. It can't get better than this, she is the happiest she's ever been.

Of course, in Equestria, there is always trouble, right around the corner. And now, a happy, fulfilled and incredibly powerful Sunset Shimmer is cursed to travel the multiverse, forced to meet other versions of herself-- Disgusted by their failures.

All she can do is keep fighting, stay strong, and hope that she can find a way back home to her love.

And maybe, just maybe, help a few Sunsets along the way.
