Rainbow dash and her friends see a comet fly out of the sky. Rainbow dash is closest to the comet and investigates. When she finds out that the comet is a filly, or other wise known as someone she is close to, she reacts quickly and takes the filly in without telling her friends. Now Rainbow dash is going to have to keep this big secret from everypony!(including Pinkie Pie!) She also has to keep the little filly from being found out or at least pretend she doesn't know the filly.
Boy, this is going to be a long ride.
Maybe I'll continue. It depends on how many views, likes, and dislikes this gets. For now I'll put it on hiatus.

This is entertaining.....
But I have a problem with rainbow being Snowdrops sister....
It doesn't feel right to me..... I don't know why.....
Heh....heh......
Please.
Continue.
It interests me....
I don't like the idea....
But the plot is making up for it.
Keep going.
Hee...hee....
Hmmm.... Seems we are in agreement, then.
Hope for the best!
Heh...heh....
Or not.....
Then run....
Good premise.
It has potential.
Needs looooooooong chapters though.
And some stuff to happen.
Cause this chapter was a turn off, bland with no real progress.
I suggest some combining of chapters in the future.
I have to say this story is intriguing and the premise is one that I haven't seen yet. The story could benefit from longer chapters but I'm a fanfic writer that shoots for a minimum of 7,000 words a chapter so I've got a bit of a bias there.
Other than that I hope you continue with this story. 
Wan is the next chapter coming out
