This is the tale of the horrifying days Princess Cadence spent in the depths of the Canterlot caves. Just before what was supposed to be her wedding, Princess Cadence is kidnapped, trapped and replaced. She spends what feels to her like eternity in these caves, unable to escape with no hope of being rescued.

Will her day ever be as perfect as she imagined?

This is essentially "A Canterlot Wedding" told from Princess Cadence's (the real one) perspective.

Princess Celestia is high and mighty in a lot of ways, motherly and mentor-like in more.  But her proteges have almost always been unicorns, with one or two pegasi, and not one earth pony in all of her over 1000 years of life. When Applejack, staying true to her Element of Honesty, even with the Princess, bluntly states that Princess Celestia understands little of what it's like to be an earth pony, the princess realizes the flaw in her understanding of her subjects. Turning to a newly reformed old friend, Celestia begs to be an earth pony for a day. What happens, nopony could have guessed.

The main six ponies are so close some might say they're like sisters. Until you start arguing the semantics of what it means to be a family. Does it mean blood relationship and shared ancestry? How about the legal definition? Or does it just mean a group of ponies one cares deeply about? The main six start arguing the definition of family when Rainbow Dash mentions her new relationship with Scootaloo.

Rarity has a very juicy secret. She has a crush on Applejack. But she's told no one, including AJ herself. The only pony who knows is a certain little sister...who MAY or may not have read her big sis's diary. A ship fic told from Sweetie Belle's pov.

Twilight Sparkle's imagination as a child was unbelievable, probably due to all those books. Which also make up the amazing Fort Book, Twilightopia's first stronghold against the country of Armor! With the help of Captain Smartypants and Private Cadence, General Twilight defends her fort against her brother's advancing army of one!

A tale of Twi's childhood told from her point of view.

Princesses Luna and Celestia are close, despite their past conflicts. But when Luna begins to spend more time with another pony, Celestia finds herself jealous of her little sister's company. Celestia has always been the one to assign friendship lessons. Could it be time for her to learn one of her own?

Scootaloo's parents have never liked one another, not since Scoots can remember anyway. Constant fights with the orange pegasus filly as a scapegoat don't help the crusader's self-esteem, though she fights to hide it from the ponies that matter to her. Can she find it in herself to face her fears and become her own pony, separate from her family problems?

In an alternate Equestria, Rainbow Dash never does her original Sonic Rainboom, thus not causing the catalyst that originally connected the Mane 6. But a strange pony has a special gift of sight, despite her haywire eyes, or perhaps because of, that allows her to see into other realities. The 6 are still special, and before Nightmare Moon returns they must find that special-ness without help from the boom. Can 6 very different ponies become the friends their counterparts are?

*A note from the author*

I hope I'm not stepping on anypony's toes with the cover art, I'm not much of an artist, so I mostly used screen caps and vectors (and one pony creator Applejack). I've got my sis working on a cover for me.
