An orphaned young filly with an unfamiliar destiny, a noble colt wanting a different life. How different exactly? As it turns out, very. Or that’s how it ended up anyway. She’s an earth pony named Skydancer, who met a run-away unicorn colt named Kuiper Belt on a train. The Everfree forest is not a welcoming place, yet they travel it anyway. Perhaps all foals need a little adventure.
It's a nice start so far. It needs a little editing for spelling and grammar reasons, and you didn't mention what pony race Cloudhopper is from which makes his bullying of Skydancer a little awkward. Despite all that, this chapter is a good introduction to the characters. Also, did your sister base this off of the Hawk Nelson song?

Yes, I guess it is kind of awkward not knowing Cloudhopper's race.
The name is based on the song
