King Sombra survived his defeat, but just. By the time he returned to form, Twilight became the newest princess of Equestria and the Crystal Empire was restored to its former glory.

He cannot take over Equestria the same way he tried before, but he has a card up his sleeve. Twilight won't see it coming, and Sombra might gain a powerful ally in the process.

And it will all begin...with a book.

Major props to InuHoshi-to-DarkPen for letting me use this. That artist is really good.

Pinkie likes Twilight, but Twilight does not like Pinkie in that way. That does not stop Pinkie, of course, and that puts Twilight in an interesting situation. What can she do to fix the problem? Or is there even a problem that needs to be fixed?

Prince Blueblood is banned from frolicking within the city limits of Canterlot. In an act of defiance, he strikes out to make a name for himself in Ponyville. Meanwhile, a lovelorn Big Macintosh pines for Twilight Sparkle, who only sees him as a big, dumb farmpony. Worlds collide when, with the help of some stolen Zebra magic, the poor, unfortunate souls switch bodies.
Now, Blueblood runs amok through the mares of Ponyville while Big Macintosh learns that being Twilight's Prince Charming is harder than it looks.The sleepy town of Ponyville is in for a rude awakening!
