She didn't think. She just jumped through the portal.

Then it closed behind her.

Stuck in the body of a human teenager, Princess Celestia finds herself trapped in the same world as her bitter student. Even as she and Sunset Shimmer both work to adapt to their new environment and bodies, Celestia is faced with an additional challenge: Sunset Shimmer is attempting to become the queen of Canterlot High, and the only way Celestia can fight back is...

...by becoming more popular.

(Book One preread by DrakeyC and Zef.)

Sunset Shimmer is a young mare who strives for power and doesn't care about anyone but herself.
Twilight Sparkle is a little filly with more scars than she lets on.
Now both of them have to make do, stuck in a world where their greatest talents are little more than a pretty mark on their clothes.

Cover art commissioned from GPizano, who draws a pretty awesome Sunset Shimmer.
