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.)

Uncle lives a very fulfilling life at his antique shop. It's peaceful and quiet for the most part, just how he likes it. Of course, he's a skilled chi wizard, so he knows better than to actually let the universe know that he's content. So he complains.

A lot.

Then one day, a basket containing three infant magical ponies arrives, and his peaceful life goes out the window...to be replaced with, perhaps, something a little more than contentment.

The universe, apparently, is smarter than he gave it credit for, because now he has "Three More Things!" to complain about to hide just how much they mean to him.

Season 5 Finale-related.
So many realities. So many horrible futures. But in yet another alternate timeline, Twilight finds herself in the Golden Oak Library with the Princess of Friendship: Sunset Shimmer. Rather than the awful futures she's seen before, she now finds herself in a timeline that actually seems nice. But that means she has a tough decision to make...

Desert Mirage lives in a world full of guns, lasers, explosives and people competing to be the best of the best. There she excels at what she does: hunting. She started as a nobody, and yet became one of the most sought-after gunslingers.

Sunset Shimmer was practically born the best of the best. Selected by none other than Princess Celestia to be her prized student... until she ran away to another world in search of power. Through trials and suffering she was eventually taught humility and friendship.

At first blush, they don't have much in common. But their connection runs deep, and sooner or later it will change their worlds forever.

Note 1: This story is told from Sunset Shimmer's perspective.

When does a game become more than that? What if it becomes a game where you are in a race against time? What if you were trapped within the darkness, and you have to struggle to find a way to return to the light? When Pinkie Pie hosts a sleepover where all of her friends, they discover that she has found a board game unlike any they have seen before, and insists the group play it.

This game is interactive... where twists and turns abound... it is a video board game where one must face their greatest fear...

Note 2: This story involves the Mane Seven playing a board game known as Atmosfear, sometimes referred to as Nightmare in other regions. Rather than go into the history of the game, I'll provide two links. One is the article about this game on Wikipedia, and the other is a YouTube of the actual video that is used to play.

My name is Sunset Shimmer, and I wanted to speak to my newest friend, the human version of Princess Twilight Sparkle, about something which I've been keeping a closely guarded secret. Because of what happened at the climax of the Friendship Games, my heart is telling me to reveal what I've kept from everyone I know. Why choose her? Because she and I are really close... in more ways than one.

While I've used the magic journal to speak with Princess Twilight, there is the other journal... the non-magical one which I've been using since as far back as I can remember. You may think that what I wrote in this journal isn't anything serious, but when it contains secrets... personal secrets about my life from past to present...secret feelings about my friends... it becomes a completely different beast altogether.

I know Twilight will be there to help just like how I helped her, but will our friendship... all of my friendships be destroyed upon revealing these secrets to her?

Note: This story takes place after Friendship Games even though all three movies will be present in one form or another. Also, the Equestria Girls comics will be present as well with some having more scope than others. There is also some mild sexual moments between Sunset and Twilight. Edit: Added in the comics to the note.

Edit: Starting from Chapter 8 and onwards, this story now has an editor: icecreammac

Edit2: Replaced the 'human' category with the 'Equestria Girls' category.
