This is the sequel of A New world, I recommend reading that story before you start with this one, but if you don't want to then here's a short summary.

-The mane 6 arrive on Earth.
-Jack takes care of them.
-Rainbow and Jack get into a relationship.
-They need to return to Equestria, Jack can't go with them.
-Rainbow doesn't want to leave.
-Celestia turns Jack in a pony and he can go with them to Equestria.

Now that Jack has arrived in Equestria, it is time for him to adjust to Equestria and to live happily, but this is disturbed by a new threat from Earth. Can Jack defend his friends and fight against his used-to-be species or will Equestria be destroyed by the human threat.

Also: I'm Dutch, not English. If you leave a dislike then I want to know why. You don't like the story, the grammar isn't good, anything, tell me.

Couldn't find a proper image for this story.
