Revenge of a Fallen Student.

After Twilgiht's friends are mysteriously taken, it is up to Twilight and her newly given wings to try to find out the ponynapper.

Sunset Shimmer was suppose to be the next Alicorn.

Now she's mad at Celestia, Twilight, and at herself for letting this happen. The only way to reverse this is to make Twilight give up her wings, and she has a plan that will rock their worlds for a long time.
