TD Harrison Powell, the human first seen in No, I am NOT a Brony, GET ME OUTTA EQUESTRIA!!! is drafted by Fluttershy to go into the Everfree Forest after one of her missing chickens. Little does he know that what he finds there will change him forever...

Luna is on a mission and she will not rest until her mission is completed. Her objective?

To snuggle with her big sister.

This is the first book of The Humanity Within Trilogy. Its sequel is What I've Done.

I wasn't always like this, a monster, running through the woods on an alien planet. I was once a man. I had dreams, a girlfriend, and a great job.
Then They came. In the middle of the night, They scooped me from my home, and... changed me.

Now I'm a beast, a demon the like of which the world I've become stranded on has never seen before, scraping by on the fringes of society, hiding from the natives, and doing my best to avoid notice.

After all, who could ever be friends with a monster?

Luna and Twilight devise a spell to go back in time and view the dream that inspired Celestia to become an alicorn.

It's not what they expected.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

(Many thanks to Easteu for the fantastic cover image for this story!)

Now with its own TV Tropes page

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

Noticing her Princess' plight, the kitchen mare helpfully offers some of Luna's "special brew" to jumpstart Celestia's day. Chaos ensues when an overly percolated princess can't handle her caffeine!

(Rated "Teen" for the single use of one naughty word.)

Daybreak's story is told here in Sometimes It Takes a Double Shot!

(Many thanks to CaptainBron3y for this live reading!)

Don't miss the unofficial sequel "A Princess Needs her Coffee", a lovely story by my wonderful friend Broman.

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?

(Thanks to Tulip for the Cover image!)

(Also now apparently has a Tv Tropes page in the making. )

Now has a re-telling in progress focusing on the Equestrians' side of things, A Stranger Among the Voices

'I looked at the reflection, and the beast looked back.'

Viktoria had never seen the mirror before, now she wishes she had never examined it. With her body twisted into a strange and unsettling new shape she must become accustomed to her new equine form before finding a way home, and along the way also return her body to normal. Her body betrays her with each movement, muscle memory working against her. Will the newly encountered Flitter and Cloudchaser be able to help her?

Even with the new addition of wings to grant her flight and escape, Viktoria has never felt more confined.

'Others see me for what I am. I only wish for them to see me for who I am.'

( Thanks go to AkuOreo for such a lovely cover art! )

( Also, seems to have a Tv tropes page in the making! )

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.
