The Little Pony Legend: Rainbow Rocks edition

That's right! I am making a re-write of Rainbow Rocks with Korra in it!! And in case you're worried I'm just going to magically make her PTSD disappear completely, well...THINK AGAIN!!! Of corse, she will just be handling it a bit better than she did in book 4, but that doesn't mean it won't still be there. She will have her ups and downs, as will Twilight. Also, Sunset Shimmer will serve a great help in their process. 

And now, a brief description. CINEMA STYLE!!!

After defeating Tirek and nearly surviving her encounter with Zaheer, Korra has decided the time has come for a change in her life and moves in with Twilight Sparkle at her new Rainbow Castle. However, once again, their help is needed when Sunset Shimmer, a former rival of Twilight, sends a message for help when three mysterious new girls arrive at Canterlot High and persuade all the students to turn their Musical Showcase into an all out Battle of the Bands. But are these girls really just in it for the glory, or are they after something far more sinister?
