Takes place a few weeks after CHS's Battle of the bands. After it, Sunset Shimmer thought she would never see the Dazzlings again. But soon, everything she knew about the Sirens will be completely overturned...
And all because of a girl named Sonata Dusk...

As usual, an enormous thanks to Graphite Sketch, who proofreaded this story and helped me improve the grammar. Also, a great thanks to SkycatcherEQ, who gave me some impressions and suggestions. Both these guys are awesome, so check out their libraries.
