First Narnia fic ever

I have just finished typing my first Narnia fanfic ever. Funny, but it's actually about Susan, my least favorite character. It may be utter crap. It's very clichè, I'm sure you can find hundreds of stories just like it. What is it about? You guess it, why Susan deceived Narnia, or how she ended up that way. I don't think that there is much that is original, but it just popped up in my mind an I had to write it! The only thing I need is a person that is good at grammar, and can read it and be honest if it's crap and I should keep going? (Maybe even give some suggestions) Yep I need a beta!
