Rainbow Dash pulls a prank on Twilight. When it back-fires, she learns a valuable lesson from the Crusaders about touching Twilight's books.

This was written for a one-shot competition a while ago, and it is my first published... well, anything. That being said, I'll never learn anything if everyone takes it easy on me, so bring it on. I already know I need work, though, so if anyone could tell me in any detail greater than "Mmhmm, you need work", that would be very much appreciated.
