It was supposed to be a simple day of rest for Twilight Sparkle. No invasions to thwart, no demigods to battle, no world-shattering revelations to deal with, not even a friend's dilemma; just the simple pleasure of a warm, sunny day spent with books, books, and more books. Maybe a friend or two later, for spice.

Then a crazy changeling drops from the sky and complicates matters with his insanity. The worst thing with the situation? He's very polite about it. And then Lyra gets involved and it all hits the fan after that.
