Lazy Pines is a small town in the high country of Colorado, easily overshadowed by the bigger sights to see along Colorado State 9. When influenza strikes the town hard, it is little more than a statistical blip in a typical flu season. No one thinks any more of it as the initial wave of infection passes ... until the other symptoms begin to manifest.

Meanwhile, during what should have been a routine trip to Canterlot, Twilight Sparkle stumbles upon a strange anomaly which turns into an all-consuming mystery. As she discovers the complex web of magic stubbornly maintaining this mystery's secrets, she grows worried what it could mean for herself and her family.

And as the residents of Lazy Pines struggle to understand -- or even believe -- what is happening to them, two worlds have irrevocably been set on a direct collision course.

I honestly didn't think there'd be much to this medical trial. I'd just have to be the guinea pig for a potential cure to a big bad disease. I figured the worst problem I'd have to deal with is sheer boredom of being in a lab for several weeks. But I soon realized that boredom was going to be the least of my worries...

When a mother gives birth to her second child, and first daughter, nobody suspected she was going to be an anthropomorphic pony. And when all else goes wrong, Damien, the brother of the newborn child, takes matters into his own hands to care for his little sister, no matter what. All she wants, is to be a normal human being, and live a normal life. Guess life doesn't go the way she wants it to.

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

Ashlyn Is kind of girl who is always trying find ways to spice up her boring life. Searching the web one day, she comes across an advertisement claiming to turn those, who are willing, into ponies that look as if they were pulled from tv! So, she sets up an appointment, and to her surprise, it was real. This is also most likely going to be the last story I will write for a very long time. My dad is gonna cancel my phone
