The unthinkable has happened. A new Draconequus has emerged, apparently intent on plunging Equestria into chaos once more. To make matters worse, Pinkie Pie is nowhere to be found, forcing Twilight and the others to scramble to find a way to defeat this new threat without the Elements of Harmony.

Meanwhile...

After strange dreams, Pinkie Pie awakes and finds herself in the body of a Draconequus. Between strange new powers that she can't control, and, for some reason, an inability to communicate with other ponies, Pinkie finds herself alienated from her friends... but finds help from an unexpected source.

"YOU ARE NOT THE REAL PINKIE PIE!"
"You probably shouldn't even exist."
"You're only a clone, you don't HAVE any feelings!"

Who was she to believe? She was barely a day old, and already she'd seen the disappearance of her mirror images, all but her. Was she just a clone? A disposable unfeeling analog?
What would happen if she became her own pony? If she became real?

Is it possible for one of the Pinkie's, the only copy left behind, to develop? To become an entirely different pony to the one that she was modelled after?

Oh, and before I forget, thanks to the amazing WerewolfNobody for the (At one point) cover art!

Jessica finds herself flung into a world she has little concept of. Everything is strange and new to her, but worst of all she cannot communicate with the native inhabitants. A world of monsters and sapient ponies, griffons and other assorted beasts is no place for a human girl.

How will Jessica cope? Without an understanding of their language how will she make her way in the world, will she even be able to ever communicate with them? Why was she even brought into the world and is there even a way for her to get home?
