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?

Curious about Five Score? Come check out the story that inspired dozens of side fics and been enjoyed by bronies for years!

Original Synopsis Even though MLP:FiM ended a few years ago, my friends and I still loved the show. Stories, merch, fan art, I loved it all. Things started to get a weird though when I found myself with a cutie mark appearing on my leg. Humans aren't supposed to get cutie marks, so where the heck did this come from? And what's going on with my hair?

More Detailed Synopsis: Five Score is an action/adventure story of the human-to-pony transformation genre. It’s unique from most transformation stories because the transformation itself is not really the point of the story. It’s the inciting incident that raises countless challenges that must be resolved. They are on earth, as a pony, and need to fix this before things get worse. Think about yourself in their hooves for a moment. How are you supposed to change back or even figure out what caused it in the first place? How are you supposed to get food or do anything on Earth without being spotted by humans? If you are spotted or captured, how would you escape? How does one even open a door with hooves!? Did anyone else on Earth get changed as well? How could you get the word out to the other ponies who are themselves hiding? Is it worth risking travel across the country to reach the others? Which of your friends would you trust to help you deal with this? And why did you turn into this particular pony? Surely it wasn’t random chance, right?

These challenges are the tip of the iceberg in this full length adventure novel There’s a lot of humor, many tense scenes, and hell maybe even a war.

But don’t just take it from me, Look what random people on the internet are saying about Five Score, Divided by Four

Vanilla Torte lives an unassuming life outside of Canterlot, never thinking much about the huge city above.

Then something lands with a thunderous crash in his garden.

Queen Chrysalis had seen first hand the power of the Elements of Harmony, so it was only natural that she attempted to create her own. However she failed to grasp what it actually took to be one with Harmony, no matter. She took her six daughters and cherished them, not as a feat of her power, but as an actual family she didn't know she could have. The six acted like the other Changelings, feasting upon love, devouring the emotions to fill themselves. They all have a part of the Original six with in them. Queen Chrysalis didn't think that would be a problem, that is.. until Changeling Fluttershy found Ponyville. She has been gone for nearly a month now, and her sisters are worried. So they nominate Changeling Dash to go forth and locate their lost sister. When Dash finds her will all be set right in the family, or will everything she knows crash down around her as Fluttershy seemingly abandons her family in pursuit of her new found friendship?

Princess Celestia has returned from a diplomacy mission with the Changelings, and she has a big surprise. She and Queen Chrysalis have fallen for each other and are now a couple. Cadence, more than a little distraught over what has transpired, plans to separate the two and prove that Chrysalis is still the evil enemy she was at the Royal Wedding.

Sequel: To Cast the Doubt Away

When one of Fluttershy's dear animal companions wanders into the Everfree, she sets out to bring him home safely - but what she finds at the center of the forest is something she didn't expect, and something that ushers in a change to her world that makes each day darker than the last.

Author's note: this story is still undergoing occasional editing as I figure out what the hay I'm doing. Some scenes may be added, modified, or removed.

Two months ago, a changeling posing as Rainbow Dash tried to abduct Twilight. Nopony was hurt, but Twilight became a bit paranoid--how could she make sure something like that wouldn't happen again? The best thing she could think of was to invent a spell, empowered with her full might as princess, that would forcibly remove the disguise of any changeling in the vicinity.

It's testing day, and Ponyville's about to get twenty percent buggier . . .

AU taking place between seasons 3 and 4. Trigger warning for one scene of implied dubcon.

In this alternate take on the ending to Season 2, Chrysalis actually triumphs, defeating everypony and turning Princess Celestia into a Changeling. However, almost immediately, Chrysalis's plans begin to go awry. For Changelings feed on love. And who is more beloved in Equestria than Princess Celestia?

After an experiment gone wrong, Twilight finds herself stuck in a body that's not hers, in a place she never wanted to be. Now she's in a race against time as Queen Chrysalis sets another one of her terrible schemes in motion, and the stakes couldn't be higher.

AU. When Shining Armor and Cadence's love shockwave vanquishes the Changelings, before being sent away Queen Chrysalis fires a poisonous beam at Twilight's chest that leaves her in a comatose state she might never wake up from. As the doctors fail to find a cure, and everypony starts losing hope, Shining Armor is determined to help Twilight return to them, but on the inside he is conflicted by the cruelty he mustered at her the night before and his failure to ask for her forgiveness before being shot. Shining won't be able to live in once until Twilight says she forgives him, but how can that be when she can't probably even hear him?
Will Twilight wake up and go back to her old life, or will Shining Armor's tortured memory forever haunt him?
