Four!
Ah. I just wrote about writing my story on a forum I used to go on. It feels very good to talk about it.
As for the language thing, I came up with how this planet actually learned it. Once they found out there were other planets out there, Katie's unknown relative Nicholas was sent to learn the other peoples' language because their own was difficult for them to use. He studied it, even took an English class or learned it from someone, wrote it all down in a book and published it for everyone to learn. He ties in with another story in the book, so you'll have to find that out.
You know what I'm glad my story doesn't have? a Prophecy. I, personally, do not like them at all. If other people like them, fine. It's just not my style.
